Hi folks, it's great the forum is active.

Getting this error; an Access Violation, but my french is very basic. :) Although this seems pretty easy to understand.

I was trying to close VWD. Incidentally it's via the Daz plugin that I'm betaing, so not sure if related to that, but doubt it.

Hi Writers_Block,

I have encountered that error a few times, and were based on different operations and settings variables. Please, try to document what you were doing that led to that error including any variables you can think of. I am beta-ing alongside you, so I will try to see if the bridge is a catalyst when closing. Did you notice if VWD is still open as a process (Task Manager), or still loaded in memory, even though it shows as closed? I get these hangs once in a while as well.

I created a new thread where we all can discuss errors, and try to help out others.

3DFineries, would you, please, transfer Writers_Block's post to that thread (and possibly this one). Thank you.

Have a creative day!

It is possible to drag parts while holding down the shift key.

I've noticed that when doing this with the simulation running, that the simulation stops; I have to stop the simulation and then restart it for the simulation to continue.

Is the shift key meant to stop the simulation upon releasing it?

The shift deformation can be used after a dynamic simulation is finished or during a static simulation.

As long as you hold the shift it keeps doing the deformation simulation.

Yes, that I realise; it seems to stop the simulation (the release of the shift) when it is already running.

Ah yes, as Shift is released it stops that's right.

As long as one holds Shift down it simulates.

If you release Shift it stops, if you press Shift again the deformation sim starts again.

Now this looks like a bug; but not sure if VWD or the Daz bridge. I loaded VWD, but I'd forgotton to duplicate the hair as a backup in case something went wrong.

So I duplicated it before I added the hair in VWD.

When I added the hair in VWD, it continually processed the hair; I had to close VWD and Daz Studio.

Got this after closing VWD; I'd been posing a dress; it didn't crash Daz though, like when I've had it crash with hair.

It's a bridge error. Once you have loaded the list of figures/actors in VWD, it will crash if you add a new node in Studio. Building internal node lists takes surprisingly a long time in studio, so I cached it to save time. I don't know, I'll have a look if I can protect the cache or connect a signal so I can clear the cache in such case.

I have just bought this fine plugin and am using it in Carrara without problems. But, in Poser 10 I cannot. Each time I run the plugin it loads the items fine, runs the simulation fine, but then when I hit the send animation to host button it immediately closes the scene and opens a new blank one. I then find two files in the VWD exchange folder. Both of them are named New Scene.pzz. One is only 2 bytes long and invalid. The other is the scene I just had up with the simulation running. The new VWD object file is now in the scene but there is no simulation data. This happens every time I run a sim in Poser. Is there a setting I need to change for this? The plugin performs w/o problems in Carrara.

@primeuser : I understand your problem. It is my fault. In Poser, you have to work with uncompressed files (PZ3 files and not PZZ files). I wanted to give this information in the documentation, but I think I've ever said it. Excuse me for this error.

I figured it out and it wasn't your fault but mine. I installed python 2.7 into my system and removed the older version. I did not go into the poser preferences and update the python setting. When I clicked the python button in poser and pointed it to the new install of python it is now working.

But, I also will not use the .pzz format, thanks.

Does the program work along side of Poser's built in soft body dynamics? I tried a sim with cloth and hair and things worked. I then tried adding some softbody movement to the character and then do a sim and I keep getting this pop up error, which I can't read - "Lecture au-dela' de la fin de fichier." I don't know what this means and it wasn't clear when I tried a translation. So, will the two co-exist with each other and is there any special way to do so?

Thanks you.

@primeuser : The error message means that you try to read beyond the end of the file. I don't understand precisely your workflow. Could you detail your actions. I think you modify a cache file but I don't understand how you can do so.

When simulating hair, if there are other objects in the scene, such as clothes that have been VWDed, the simulated item (hair) will try to pose but then dissappear out of the scene.

Writers_Block posted at 9:09PM Fri, 01 July 2016 - #4274330

When simulating hair, if there are other objects in the scene, such as clothes that have been VWDed, the simulated item (hair) will try to pose but then dissappear out of the scene.

Let me know what you need for this and I can describe in more detail; I can repeat it fairly easily (I hope).

Set up an animation; let it run.

Reset the animation.

(maybe change the paramerters)

Then use the Shift key.

VWD crashes; or gives an error message. I seem to recall posting it for something else. I can grab one if required though.

The error message can't usually be got rid of; holding down escape just cancels the current window error - another pops up. Usually have to kill VWD with the Task Manager.

Not sure if this is a bug.

Run an animation until it completes.

Press escape to stop it looping.

Use the shift key on each frame (that is required) to fine tune the pose.

At this stage the simulation runs fast.

Whilst the shift key is pressed, adjust the position of something.

Now the simulation runs very (very) slowly.

Holding the shift key is not the problem, but adjusting the position of the verts.

Adjusting the position with the mouse affects the speed of all frames, not just the current one. So if don't tweak all before manually moving the dynamic simulations can become incredibly slow.

@Writers_Block : For the hair, I don't understand because I regularly make simulations with hair with some clothes VWDed in the scene. Could you give me precisions on the test, Poser, Carrara or Daz Studio? It is as if some nails deform the hair far in the scene? Have you the time to see where goes the hair? VWD starts to be ready at the level of its working functions. I have now to stabilize it. I will make the tests you post in this thread to find the solutions to these problems I will make a test with a shift key modification on several frames to see the speed of the animation. Normally, the animation would not have to be affected by these modifications because the vertices positions are recorded in a file.

I'm about to go to bed, and tomorrow will not be possible; I will check I am still getting the errors and let you know what you require soon.

Using the Carrara bridge. am getting an - obj does not exist error - when hitting the cloth button from the list of host objects. Just to make sure, I exported the cloth object as an obj and did a fresh start in Carrara. Loaded my figure and then imported the cloth object as an obj to the scene. Used VWD to list the host objects. The figure and the cloth prop both appear in the list. Select and load the figure from the host list as the collision object. Works fine so far. Select the cloth object from the hostlist and click the cloth button. VWD takes some time to process then returns an error saying that the cloth object's obj does not exist even though it was selected from the host list.

diomede: This might be better answered by philemot in the the thread "Carrara bridge to VWD questions". He set it up to address any issues regarding the Carrara Bridge.

I don't use the Carrara version, but I experience this on a regular basis with the DS Bridge. However, I believe it might be environmental, and not the software, because this only happens on my Windows XP laptop, but never on my W7 PC box.

For me, it is related to button clicking. If I simply left-click on the VWD buttons (collision, cloth, etc.) it will start to process (as in your scenario), but fails to create the OBJ, and I receive same error message. The work-around I have found to work is to left-click and hold button for a solid second, and then release. This seems to allow the OBJ creation function to finish, and everything works fine from there.

This hasn't been a repeatable bug on other systems, so you might be the second to encounter this (as far as I know). Please, try the slow-click method, and see if the process finishes without error.

This, of course, is just conjecture, because although similar, there are differences between the two bridges, and only philemot can really give you a proper diagnosis of the issue based on your variables.

It happens when the there is an extra collision item in the scene. This time it was an item that had been VWDed, but I've had it happen with others - last time I saw it was with hair, and that was a static simulation. This was dynamic.

The image shows a bikini bottom that had behaved normally, I think until the simulation had run, then it vanished at the end. It might have been before, I just noticed it gone; it did start off working. As you can see, it doesn't look much like a bikini now. Took a while to zoom out and find.

Since installing the new releast of VWD, I'm getting the following error; I tried it once and it worked, but since rebooting comp it doesn't. I've not changed anything in VWD or the bridge folders since installing. I installed on a different machine and I get the same, although I'm using the same Daz library. Sometimes I get the error on the right as well as the left, which is why I posted here as well as in VWD bridge.

re the above; reinstalling windows from a disk image solved it. So no clue what got corrupted.

On the new Version of VWD, I've notieced that for hair, self-collision is selected by default, although it is still greyed out.

---

New issue, anyone been able to simulate clothes, but not hair?

That error when trying to do hair, but cloth works fine.

OK edit has timed out.

Reverting to the old version of VWD, allows me to simulate hair. I kept he new version of the .dll that came with the new version though.

re post @4277127

Wasn't expecting it (but since the new version of Daz bridge I retested), but still getting the error when trying to simulate hair in the new version of VWD; the old version simulates it just fine.

Hello Writers_Block, I will try to reproduct this error. Excuse me for the delay.

Just to report that I get the same error as Writers_Block when trying to simulate. My steps are:

Genesis 3 Figure > Collision Object, default settings

(Hair choice) > Hair > Use Vertices Neighborhood, checked, distance 0.5, Softness 0.1, Distance min 0.30, and then apply parameters and generate.

Hair parameters: Genesis 3 Preset selected, Computer head vertices, show hair vertices, generate springs and finish.

Simulation: Inertia checked, everything else at default. Start static sim is followed by the Violation d'accés a l'adresse error message, exact same as Writers_Block. I am using the newest version of VWD as well, 64 bit on Windows 7!

Hello,

I have a problem with this bug because I can't reproduce it on my computer.

I need other informations to find the problem.

The problem exists also for clothes or only for hair? The problem exists only on G3F? The problem exists only on the last VWD version?

Could you tell exactly when this error occurs. At the hair creation? during the simulation? when you want to send the results in the host?

In the last version I had many problems with Hiddenlines shader. Perhaps this error comes from this shader. I have to make tests.

For the persons who work on Daz Studio and Poser, Have you the same problem on Poser. (With G3F and a hair, as G3F can be used on Poser now).

Sorry for that.

Sorry for that.

The problem exists also for clothes or only for hair? - The problem exists purely for hair.

The problem exists only on G3F? - Other figures I've tested ,Genesis 2 Female and Genesis, experience this

The problem exists only on the last VWD version? - The problem wasn't in the last VWD, although my testing of it was very brief before you sent me the new version!

Could you tell exactly when this error occurs. At the hair creation? during the simulation? when you want to send the results in the host? - Personally for me, the problem begins when I press 'Start static simulation'!

Thank you Ashfire45, The problem exists with dynamic simulation too ? Could you press the "Reset all parameters" button in the tools tab And redo a test, Please. Just another question. Could you tell me the full path of your VWD directory. The folder where is the VWDClothAndHair.exe program. Thank you for your help.

Could you tell me the full path of your VWD directory. The folder where is the VWDClothAndHair.exe program. Thank you for your help.

Unfortunately, reset all parameters made no difference. I have tried many varied settings but it seems regardless of the figure, hair, or settings used, that it simply does not want to work with hair!

Good question! My path to VWD IS:

C/Virtualworlddynamics/VWD

I've tried deleting the folder and copying a fresh version of VWD, but do you think I'd be better trying another location/folder to see if that helps?

Hi! Just to report that I tried out my own suggestion, and deleting the VWD folder and creating it under a new name worked! I deleted the folder, created a new one called 'Dazdynamics', pasted VWD in, and now simulating hair is working!

I had this problem. I have resolved it by pressing two buttons in the Utilities Tab:

• the "Reset default parameters" button
• the "Delete all exchange files" button. Pressing these buttons seems to resolve the problem.

I have to make tests and find the exact problem. Having a short path for VWD seems also to give best results. Personally, I use "C:VWD". These solutions are not definitive ones but they allow to resolve the problem.

Please, tell me if this corrects the error.

I already use C:VWD

I'll try creating a new folder under a different name.

Ok clicking the resets as Gerard stated seems to have fixed it.

the "Reset default parameters" button
the "Delete all exchange files" button. Pressing these buttons seems to resolve the problem.

As my folder was already C:VWD, I left it until after trying the reset/delete; it works so not changed it.

I notice that when importing hair, the greyed out self-collision is no longer checked. When I was getting the error with hair, it was checked.

@Writers_Block : Thank you for this very useful information. By default, for the hair, I make the self-collision unchecked and greyed because self-collision on hair would generated a very long simulation and the result would not be good. I will try to find why the check box was checked for the hair. Thank you.

You're welcome.

In p11, lately I have been getting a traceback...line 17...module error. I cant do a screen shot because it disappears quickly after I shut down poser. In VWD, cloth or hair, default parameters, after I click start dynamic simulation, it freezes. I end the program. When I shut down Poser is when I see the error. Just started to see this more after the latest updates.

'I'm paying for this movie. I want guns'

It also says, 'invalid scene object'.

'I'm paying for this movie. I want guns'

@NolosQuinn : Is the program made this error every time or it's only for a few objects? In any case, could you tell me the name of the objects with which you have these problems. Your error seems to be a Python error, but there is no communication between VWD and Poser when you press on the "Dynamic simulation" button. Could you tell me exactly the precise time where this module error appears.

@VWD Looked at memory usage, said I had 28 threads going for VWD. Reduced it to 2 threads, still had freeze issuse. Unchecked Use Multithread and that seems to have been a memory issue. So far works 8 of 8 times without any problems. Sent to Poser, now rendering animation. Yeah!!

'I'm paying for this movie. I want guns'

Hello NolosQuinn: In fact, you say you cannot use VWD in multithreaded mode? Could you give more informations on your computer.

Wow...three days, dozens of attempts and not one even remotely successful simulation. I don't know where to start. It could be (probably?) related to my unusual computer layout so I'll start there.

Win7 64 bit and NOT connected to the net so there's AV or firewalls. All excess Windows crap is shut off so it boots in a couple of seconds.

C (an SSD)-is for windows only. I don't let anything store it's files or temp there.

D (a partition on the SSD) is for programs only and again, nobody stores temp stuff or data there.

F My graphics drive where my runtimes and Daz content live. All my graphics for still and 3D live here.

There are more drives for video and motion graphics but they don't matter.

While I have Poser, I treated the install as if I didn't. The VWD folder went to the root of C: and the Daz bridge stuff went (as instructed in the pdf) in F:Daz Content/My Daz 3D Library/Scripts/VWD Bridge. I had to create the "Daz My Library" directory since I didn't have one (I hate how Daz wants one to arrange their content).

The bridge starts fine and I followed the tutorials (my French NOT being as rusty as I thought it was). I went big to start, with V4 sporting a ton of Bridal wear, long skirt, train and a long veil. Things went fine until 'nail to collision'. It locked up and I had to use Process Explorer (PE) to kill it and Daz. It seems that the VWD would go to 25% CPU usage and stay. Even after it was killed in PE, Daz would now be at 25% and unresponsive, forcing a kill in PE. I went progressively simpler and simpler finding that it was impossible to grab just one layer-row of pixels since so many of the items I was using had more than one layer. Finally I gave up and tried using a simple small plane turned into a figure and pinned above her head. I wanted to make it drape down like a veil. That actually worked for a few iterations until suddenly, the plane shot off the screen somewhere. Aaaand of course, I had to kill VWD with PE and then Daz too. I then resorted to very simple scenes with V4 and a simple negligee. That started draping then Wham it shot off the screen. Both VWD and Daz needed to be killed with PE. During all this I only had one actual error message. Yes, I dutifully deleted Exchange files every time I started VWD.

Got any ideas?

Kittykat, is the DS bridge for sale now? I'm not finding it!

Hello Kittykat, visibly no simulation runs until its end. It seems the dynamic element (Cloth or Hair) goes always out of the screen. This could happen is the animation is too fast and the stress too important for the simulator.

To understand your error, I need some informations :

• You say you use the Daz Bridge, but have you made some tests with Poser. I remember you said me you own it.
• Have you made some tests with a static simulation.
• Have you uncheck the "Fast move" checkbox. This function helps to keep the stability of the simulation when the collision object moves quickly.
• Have made some tests by increasing the "Nb sub samples" value. This helps when the animation is fast.

I have to know if the problem comes from the simulator or from the animation.

I am sorry for this problem. I don't think it comes from your computer.

@ Kittykat - you actually have "Daz Bridge stuff" in your VWD installation package?

@ VWD - Kittykat 'ignored Poser in the VWD install process', the only time Poser was mentioned.

Kittykat did however mentioned Daz Library Script subfolder, and "force killing" Daz Studio.

So it seems it's all Daz from that point on, and no Poser, at least from what's been presented.

Agape and myself are confused by KittyKat having installed a Daz Bridge! Which, allegedly came together with KittyKat's VWD installation package!

Mysterious indeed!

Unless...KittyKat got the Carrara bridge half-working in DS... or even got the Poser pythons installed into Daz Library and then got it half-working in DS...

The bridge is still in review. I have small adjustments to do and I'll resubmit it. Kittycat bought it directly from me (paypal sale). Just send me a sitemail if you wish to do so (although I'd rather sell it through rendo store).

If you force kill VWD with the PE, you have to tell Studio bridge there's no need to wait for order for it, otherwise it'll be waiting for ever. The way to do it is just to restart the script. It will close the waiting loop. A second start will relaunch VWD.

Cloth shoot of the screen in VWD when parameters are not adequate. After importing the collision and before importing the cloth, go to the utilities menu in VWD and choose "reset parameter" (or something like that, I'm at work and don't have VWD installed on that computer, it's just from memory).

Thanks Philemot. I will try and hold out a little longer!

Wow again...double and even triple wow. That was two evenings of wasted time and frustration I'll never get back. I didn't initially respond since I didn't want to say anything about buying the two programs directly from the authors since I didn't think they wanted it publicly known. Now that it's out, I'll say that I wish I'd bought them through Rendo (as much as I hate and despise the company) since it would be a simple matter to get a refund if I have to...and I'm leaning that way.

Taking the advice from the forum here, I launched back into attempting some simple static drapes. Reboot computer (just to start fresh) and ensure (yet again) that all VWD and Daz bridge files are where they're supposed to be. I loaded V4 in a long negligee and posed her kneeling to try and make the skirt drape down over her back, butt, legs and finally the floor. I encountered all manner of problems with selecting vertices. Selecting 'visible only' is inconsistent in operation, operating sorta correctly sometimes but mostly not selecting anything. I resorted to using the 'Alt' key to deselect the ones I didn't want but that frequently deselected everything. Trying to add the pixels around the neck strap only added to the frustration. Numerous maddening attempts later I had a selection. 'Nail to ' Collision' actually worked. Using the parameters suggested I set a static simulation running. Wow! is this slow. and Wow!, almost nothing is happening except for some bunching around her legs. I let it run for many minutes while Process Explorer (PE) showed lots of activity. That's good, at least it's running. I started and stopped the simulation a few times with no effect that I could see. After maybe twenty minutes I stopped it as a useless exercise. Over the next hour I retried this same drape a couple more times with similar (lack of) results.

Assuming that this was too complicated for VWD I posed V4 with a hairdo and placed a medium resolution blanket over her head to try a simpler drape. I chose her hair and figure as collision objects then hit 'nail to collision'. Nothing........zero......rien.....From my previous experience I'd learned that VWD seems to be unable to apply collision to more than one object at a time. Wow, that's kinda useless. Poser can drape an item over all kinds of things at once...I've done it the few (rare) times Poser didn't crash on me. Anyway, I tried again with just the hair selected for collision. This time it actually started to move but Wow!, it's still painfully slow compared to the same exercise in Poser. As the drape s-l-o-w-l-y crept along it looked like crap. The material was all bunched with spikes and dents everywhere it approached the hair. Then it started sucking INTO the face area where V4's head would be. I started and stopped it once or twice. This didn't seem to effect anything so I let it run it's slow and painful way along until ZIP!, true to form, the blanket shot off the screen into...?

I tried it a couple more times, ensuring that I was following the steps correctly but got pretty much the same thing. I have almost zero experience with dynamics but the few times I'd fiddled with it in Poser impressed the merde out of me. I set V4 beside some furniture, stuck the same blanket (with opacity set low so that I could see through it) over her head and watched as it smoothly settled down over her and the furniture. I experimented with different material settings (density, stiffness, friction etc) and got quite a kick out of how amazing (and quickly) it worked....at least when Poser itself wasn't crashing. (I use Daz not because I like it but because it's been completely stable for me while Poser crashes and locks up constantly). So now I'm wondering why an expensive ($90 bucks Canadian) program can't operate at least as well as Poser's native dynamic capability.

And wow, as I'm twiddling my thumbs watching nothing happen or trying again (and again and again) to make a selection, I'm getting more and more critical and less willing to overlook the massive failings. The GUI is horrible with buttons just stuck on. I can't resize the window. My main monitor is 2560 X 1440 making the VWD window a small strip down one side that I can't move or resize. When the window is maximized it wont respect the task bar or other windows. I tried to take some screen shots with 'Greenshot' but the 'save as' window couldn't butt in front of the VWD window. I had to shut VWD down, do a screenshot and move the resulting window to another monitor so that it would show up there from then on. The task bar wouldn't appear unless I first clicked the corresponding area on another monitor. When I shut VWD down it doesn't usually really shut down, it leaves parts of the GUI on the screen forcing me to (as suggested) restart it from the script icon. When I do this I see nothing for several minutes when I'll get (finally!) the box telling me that VWD is already running but will be shut down. Only once did I have to resort to using PE to kill VWD and Daz...a small victory. I get the impression that the two authors have little experience with real consumer programs, GUI's, and usability. One of the jobs I do at my work is to provide imagery support to aerospace engineers (many of whom are programmers). I populated a few areas in the data tracking programs with video of boring technical stuff. The program they use reminds me of VWD since it has piles of buttons and selections just stuck in a simplistic grid with no concern for looks or usability. It's an engineering tool and they couldn't care less how it looks. That's fine for industry but won't fly in the consumer world, even Adobe makes their programs look nice, and absolutely worries about workflow and the interface.

And lets talk training. If these programs where free I might excuse the total lack of documentation and poor tutorials. I paid big money for these, $90 Canadian, that's a third of the price of Poser Pro...Wow! For this kind of money I expect more than a bunch of videos that only show a basic walkthrough. There's a zillion buttons and selections available, what do they do? How am I supposed know what they all mean? Daz loves to do this and expects people to return endless to the forums to ask the same basic questions over and over again because they refuse to provide real documentation. Has anything been written down or does all the knowledge exist in the author's heads? For this kind of money ($90 CAD!) I expect full, complete, and comprehensive documentation. I bought Reality last year (for a measly thirty bucks) and it came with a very complete and well written pdf manual.

Ahhhh you're going to say, VWD and the bridge are still in Beta or they're not complete or it's still in development.
SO WHY IS IT BEING SOLD? Would you buy a car that had only half the parts ready or who's engine only ran up to 40 KpH? Would you see a movie before it was finished? I'm sliding down a nasty slope here and getting madder by the minute. The authors want money (BIG money!) for programs that JUST AREN'T READY. Are they that desperate for money? I love to support the little guy. I bought Reality, I also bought a couple of plugins being developed by the Blender community. But these (VWD and the Daz bridge) seem to be less than a serious endevour by people who know what they're doing and more of a pipe dream by people with big goals. I do blame myself for getting overly enthusiastic and buying it before it's properly ready (if it ever is) but can you blame me for wanting this? Dynamics in Daz are a dream of most users. I've had reasonable success with the Dyncreator (a very reasonable eight bucks) and am kicking myself for blowing big bucks ($90 Canadian...argh!) on VWD. I do, however, want to kick Rendo-short-sighted-and-desparate-for-money-osity for allowing an unfinished, buggy, undocumented program to be sold here.

In conclusion, I want my money back guys. I'll keep a close eye on this and maybe try it again if it gets fixed and documented but now I'm stuck with a program that just doesn't work.

I instructed Paypal for a reimbursement. You should have your money back very soon. Sorry it didn't work out for you.

Successful installation, static and dynamic simulations, using default settings. Genesis with a simple test tunic dress (with morph). 60 frames animation.

Getting the hang of it...

Overall rather smooth start. I keep a screen grab for the 1 occasion of VWD + DS freeze/hang in case (happened when I randomly pressed button the first time I launched VWD) After I followed VWD instruction step by step, all work as expected.

Side Info: Instead of /My Daz Library/script, as specified by Philemot's (very clear) install guide, I copy-pasted the Daz Bridge Script into the C:/Program Files/DAZ 3D/DAZStudio4/scripts (typically all my scripts go there) and it works fine too; so far anyway :)

Will practice and play some more!

FYI my system: Win7 64bit; Daz Studio 4.9.2.7.

I placed VWD install folder in my A drive. Folder structure: A:/3D FILES/DAZ FILES/VWD/VWDclothandhair.exe.

I placed Daz Bridge Script in my other drive C:/Program Files/DAZ 3D/DAZStudio4/scripts/VWD Bridge/VWDpython.dse (this is a my custom path VS Philemot's official/suggested path = .../My Daz3D Library/scripts/)

I placed Daz Bridge Plugin in my other drive C:/Program Files/DAZ 3D/DAZStudio4/plugins/VWDsupport.dll

It all launched as expected the first time.

I successfully simulated a static frame the 3rd try.

I successfully simulated a dynamic 60 frame next.

Will report some more.

That's kind of you. I sincerely hope you get this working someday.

@kittykat98 : I sent your refund to Paypal. I don't understand something, a demo version exists, if this version didn't work correctly on your computer, it was not necessary to buy the full version. You weigh down a program that you never was able to run correctly. In a previous message, you spoke about a denigration campaign at Daz 3D. I think Daz has found in yourself a very efficient detractor. You made a splendid work. I suggest you to ask for a job at Daz3D.

I also wish to add, VWD itself came with a very thorough and detailed step-by-step tutorial, with illustration too. All 58 pages of it!

I say that as a user with some basic experience with Carrara's Bullet soft physics, Sparrowhawke's cloth deformer plugin, and also iClone, Poser, and DynCreator for Daz Dynamic Clothing Control.

VWD's English may not be perfect, but the sincerity and time investment into creating VWD documentation will be self-evident to any beginner to intermediate CG users.

Philemot's Daz Bridge also came with clear enough installation guide.

More report later...

Cheers.....

I honestly don't understand why some computers have issues and some don't. I built my own computer 4 years ago for more power to use my 3d programs and I don't have problems with it. I bought the program directly from VWD before it was on sale here. It wasn't a secret. He made it clear that he would sell it privately. I cut my teeth in 3d in Poser 4 in 2000 but now prefer DS now. I bought the Poser version to play with it in Poser. It works great! I have chosen to wait for the DS version instead of buying privately. Kittycat, I don't know what the problem is but I don't think its the program. You admitted that you have a strange computer configuration so to blame the program for not working isn't fair. Others aren't having issues. I don't have issues with Poser. I have the newest version and it works like a charm. Poser is unstable on your computer so you can't use it. The common denominator here is your computer. It definitely has issues. I am glad the developers were kind enough to give you your money back for a program that doesn't work with your computer but I think, in all fairness, the issue here was not the program.

I keep getting this error and as I don't speak french I have no clue what it it. "Lecture au-dela' de la fin de fichier." Can someone clue me in? Thanks.

primeuser:

I have documented that error a couple of times, and it loosely translates to "Reading beyond 'from the end of file". VirtualWorldDynamics can help you, but it could be a possible error from different situations.

Please, can you describe what you were doing (workflow, buttons pressed, etc.) which led to error pop-up, so VWD may help you better. Also, your PC environment to help narrow down variables.

Have the daz bridge installed, Daz 4.9, however when I click the Host List nothing shows in the window. Script and plugin saved to locations shown in instructions, but instead of A:/ I use C:/. Is there another step(s) that I am missing?

Also, I ordered VWD directly, can you send the updated 58 page manual or link. Thx.

'I'm paying for this movie. I want guns'

When I first installed everything, I was having all kinds of problems, errors galore. When I was just about to quit, something came to me...I was using the latest Daz 4.9 Beta. I had installed the plugin into the main program instead of the Daz Beta plugin folder. Once I put it where it belonged, it works great! Not one single error since!

Okay, walked away, came back and deleted daz bridge and related files. Started over, followed instructions step by step, slowly. Success! Now running sim. Waiting to see results after being sent to daz. Should be no problem.

'I'm paying for this movie. I want guns'

Not an error exactly but a suggestion for the documentation. When there are parameters described, it would be nice if there was an explanation of what increasing and decreasing the value does and what some reasonable maximum and minimum values should be. For example, "The «Stretch» value sets the value of spring stiffness of the edges of each face in the mesh." What does increasing the number do? Does it make it more stretchy or more rigid? What are some reasonable ranges? 1, 10, 100, .0000001?

Good valid points RobotHeadArt...

I worked out eventually that Stretch increase is MORE stretchy. I can't give a number because changes in other value in any other Parameter panes will affect this stretch outcome. Stick to 0.1, 0.2, when in doubt, is my narrow-down method.

The next line has a small error: the manual says 'Stiffness', when it actually is Softness. Anyway, Softness increase is MORE softness. True for all Softness settings.

I've been informed that VWD is working on the next iteration of documentation more tailored for Daz Studio users. So keep the feedback coming...

Oh the joy of high variable cloth sim!

Meanwhile don't stop experimenting and pushing button randomly like I do!

One crash pattern observed:

Sim actors can be the usual figure/prop, or both Daz primitives with sufficient vertex density.

-after dynamic simulation, press Vertices Tools + Vertices Group tab

-try to load material group = produce error message

-nothing can be done any further for this simulation session

-attempt to exit VWD = crash hang

-Task manager to force close VWD

-In DS, everything seems normal. Click on VWD action button to launch next sim session

-DS crash hang

-Task manager or Ctrl Alt Del to force close DS

Sorry for the delay. I have windows 10, 16gb ram, GTX760 card, Intel 6 core. I have tried numerous times using poser to get the plugin to work. With the older version of the plugin it would give me the beyond end of file error about 50% of the time and then not work afterwards. The newer version I have now gives me the error almost 100% of the time. I think I have gotten it to work once. I also have the Carrara bridge and it also worked better with the older version. The newer one gives me wild, unpredictable results. I just bought the DAZ plugin also and have not been able to get it to work correctly even once. Again, very wild distorted results. I have gone back to using the previous version 408.2976 I think it is.

@RobotHeadArt, @Mythico : Your idea will be very useful. In the interface, each values has limits. These limits are just here to avoid instabilities but they never have been described precisely. In the new version I will try a define some behaviours even if I don't know if I will name them as existing materials. A great work on the program and on the documentation.

@Mythico : I will look at the problem you have had.

primeuser:

I don't have W10, so I don't know if it could be environment stability issues, but I am curious about you stating the latest version being unstable, and going back to stable version 408.2976. Version 408.2976 should be the current, latest version. Could you please double check this, including reactivating your latest version and verifying the version number in that build. I tried to test for all variables for stability failures, but W10 is outside my testing scope.

VirtualWorldDynamics:

Could you please take a look at primeuser's issue as well. His system specs are a couple posts up from this post, but you missed it, and his initial post.

Mythico:

I did not test for this variable. I want to see if I can replicate as well. Just curious to your work-flow, why were you selecting materials for vertex selections at this stage after an animated drape? Were you trying to pin vertices, so you could further work on cloth with the push/pull draping?

@primeuser : Excuse me. I regularly look at the forum and I haven't replied to your problem. Feel free to send a direct email on virtualworlddynamics@gmail.com, If I take too much time to reply on the forum. The message you have, says that you try to read data after the end of the file. Into VWD, when I have to read a file, I write this file with another name and I rename this file when all the process is completed. I looks like a file is read in VWD at a time where it is not fully written by the host.

Could you give me very precise informations on your problem.

• This error appears every time at the middle time of the simulation?
• This error appears for clothes and for hair?
• This error appears for every lengths of animation?
• The simulations you had with a good result are they repeatable or they work correctly sometimes and have the error the other times?

Could you give me the names of the dynamic elements you use. If I have them, I could make some tests. I suppose the static simulations work correctly.

Perhaps, could you send me a short video showing the display of the message. Perhaps I will see something that will help me.

Visibly, you have the problem in all the versions. The problem comes certainly from VWD and not from the bridges.

I look at your reply to begin to find your error.

Excuse me again for the delay.

Thanks VWD and Philemot, great work.

Just to keep you busy on a Saturday night here is a description of a couple of problems I have come across. (apart from trying to run it with too many objects in scene or trying to run it with No Sub Samples of greater than 20 with maximum No iterations of 7 or greater)

Error1. Windows10Insider14915 only, If I add a Figure as Collision object before adding a Wardrobe item(or items) as Collision objects and then add a Cloth(or Hair) item, I get a Violation error when starting simulation(or Generate springs for Hair). See image "vwd error v42 figure first". I get the error every time when using elements below. However error does not occur on other combinations of Figures and Wardrobe items (sorry I don't have list of elements that it worked ok for). If Wardrobe item(s) are added before Figure then error does not occur when running Cloth simulation. This then works ok for Cloth (e.g. Nwear_shirt) dynamic simulations, however Hair simulation has further issues, see error2 below.

Error2. Violation error when starting/running Hair simulation. Have run Static simulation with Collision elements Nwear_shirt and Victoria4.2 and Maria Hair as Cloth element to create element Maria_Hair_1. Restart VWD and add Collision elements Nwear_shirt and Victoria4.2 (in that order) and then add Maria_Hair_1 as Hair. Select Victoria4.2 as collision actor for Hair. Select Preset of Victoria42 DAZ in Hair parameters. Show hair and generate springs. Start dynamic simulation. On Machine 1 simulation starts but fails with a "Bridge to VWD crashed..." error anywhere between frame 1 and 235 (of 311frames). See image "vwd error hair v42 machine1". Once error message appears then unable to close VWD. When trying to close VWD it brings up a Violation error message in VWD. Only way to close it is to kill VWD process. On Machine 2 simulation does not start, it immediately brings up VWD Violation error message. See image "vwd error hair v42 machine2". However am able to close VWD after error message has been displayed.

I was able to complete a short 100frame Hair simulation on machine 1, however it was a once only event and all other attempts at dynamic Hair simulation of 100frame or more failed.

Elements; Victoria4.2 Nwear_shirt by Masanori Kobayashi Maria Hair and OOT Hairblending by outoftouch Animation - blank aniblock, start-(N),3x forward_1_cycle, stop-(N), blank aniblock, start-(N), corner right (for total of 311 frames) from aniMate Walk Construction Kit by GoFigure Hongyu's Bikini 2 for V4/A4/G4/Elite by hongyu (not part of simulation)

Machine1 Windows10, DAZ4.9 and DAZ4.9.3.71PublicBuild, VWD 1.0.408.2976 Machine2 Windows10Insider14915, DAZ4.9 and DAZ4.9.3.71PublicBuild, VWD 1.0.408.2976 The multithread values are as set by VWD. Both machines have more than adequate system and video ram.

@npayn : Thank you for your very precise informations. Have you the possibility to make the same tests on Poser? I believe I own Maria hair (not sure!). I make some tests and I give you a reply. Have you made a test using the "Reinit all parameters" function. This function seems to resolve some problems. I don't know why because it just resets the parameters. Thank you to occupy my lazy weekends ;-))

@npayn : I have made a test with Maria hair in Poser and in Daz Studio. On my computer, all works correctly.

I send you a video showing the result : https://drive.google.com/open?id=0B9c39Rz2Ec-JRHk4TjR6U0pMeVE to show you that the simulation exists.

I begin to have some ideas about these errors. Can you confirm me that the messages appear always during the simulation.

Mythico:

I couldn't replicate your errors with animated simulations on either of my systems (WinXP_x86/Win7_x64). I tried both simple, and a complex animation simulation that ran for over 4 hours. I was able to use all selection parameters, including material selections without errors at the end of simulations, and both individual poses and full animations returned to host (DS) without issues.

Please add more details (environment, meshes used, etc.), so VirtualWorldDynamics, and/or Philemot can try to help you better.

Poser 11, V4 and L.A. Hair by Aery Soul (or whateva name they're using now) - Getting 'object not found' error.

What parameters are you using or can be used for the hair?

'I'm paying for this movie. I want guns'

@NolosQuinn : Thank you to give me all the informations concerning your environment. This is very usefull. The "Object not found" message appears when the delay between the start of the importation and the real importation of the file is too long. I have to look at the program but I believe this time is 30s. Some hair have many vertices and the preparation of the importation can take a lot of time. Perhaps, I have to increase this value because the new hair particularly have more and more vertices. Have you this problem with simple hair. Could you tell me the path of the VWD program. I suppose you only use the Poser interface. Have you tried to remove all the files in the "Exchange" directory, by pressing the button or in the Windows Explorer. Have you tried to press on the "Reset all parameters" button. Philemot told me he has to do that regularly. I've looked at the program and I don't understand why this can resolve the problem because I only change the values in the interface.

@primeuser : Just a thought, could you make a test. As I said before, the problem you have is linked the reading of a file. During the simulation, the only file the program has to read is the animation of the collision element(s). This reading is made at each frame, but you can read the full animation and then start the simulation. This action has an advantage and an inconvenient. The advantage is that the simulation runs more quickly. If you want to run several time the same animation, you keep this advantage and you don't have the inconvenient that follows. The inconvenient is you have to wait that the importation of the animation is fully imported to start the simulation.

1. you import a collision object with an animation and you uncheck the "New animation" check box.

2. When the character is imported, you open the "Collision" tab again and you press on the "Record" button. The animation is played in the host and in VWD. At the same time, this animation is recorded in VWD. You can verify the recording of the animation by pressing the space bar. The animation must be played in VWD and not in the host. You can then press the Up key to return to the begin of the animation in VWD.

3. you can import the cloth or the hair and make the actions you want on the vertices.

4. When all is ready, you can start the simulation. At this time, there will be no exchange between VWD and the host. The simulation must go to its end without any problems.

Could you tell me if this method resolves your problem.

If we want to stay logical, the problem, if it exists, should be during the importation of the animation.

I hope the method will help you.

Thanks VWD, I tried using the "Reinit all parameters" function but both computers still fail.

On the Windows10 computer, if I use just Victoria4.2 (as Collision) and Maria hair (as Hair) the simulation runs ok. (e.g. like in your example)

If I use Victoria4.2 and Nwear_shirt (as Collision) and Maria hair (as Hair) the simulation fails during the dynamic simulation creation with a "Bridge to VWD crashed..." error.

It did work just the once, with a short 100frame animation. But has failed every other time I have tried.

The Windows10Insider Preview computer gives a Violation error every time I run a Hair simulation.

It fails with just Victoria4.2 (as Collision) and Maria hair (as Hair).

If I use just Victoria4.2 (as Collision) and Maria hair (as Cloth) it runs ok.

If I use Victoria4.2 and Nwear_shirt (as Collision) and Maria hair (as Cloth) it crashes with a "Bridge to VWD crashed..." error.

When I have some time I will look at the system error logs and see if I can see why Hair simulation is failing on the Windows10Insider Preview computer. The Windows10InsiderPreveiw is not that different from standard Windows10 so I should be able to find a reason why it fails on one and not the other, just need some free time. When I see this type of error in my own code I usually look for 32bit to 64bit or 64bit to 32bit errors.

I do have Poser on the Windows10InsiderPreview computer but have not used it for a long time. When I have time (might be as late as next weekend) I will give it a try in Poser and see if VWD Hair simulation works when using Poser on the Windows10InsiderPreview computer .

Well the weekend is over so back to the grind for the next five days.

Yes, have tried using the "Delete all "Exchange" files" and "Restore default parameters" functions. I have not tried deleting exchange files in Windows Explorer. Will give that a try next weekend. VWD path on both computers is C:/VWD

Regards

I think I have fixed my problems. I have only done two simulations tests but both worked fine.

The problem appears to be the version of Python I had.

The Windows10InsiderPreview computer had Python 2.7.12(64bit). I uninstalled that and installed Python 3.6.0a4(64bit) and have been able to run Hair simulations of 311 frames with Victoria4.2 (as Collision) and Maria hair (as Hair) and also Victoria4.2 and Nwear_shirt (as Collision) and Maria hair (as Hair) without error.

My Windows10 computer has Python 3.5.2(64bit) installed. When I get time I will uninstall that and install Python 3.6.0a4(64bit) on it and see if that fixes the problems I was having with it.

@VWD - Yes, I've done all of the above. I used a simpler hair for now but will go back and test again later this week.

'I'm paying for this movie. I want guns'

banal question, I'm sorry for bothering you all: may I use vwd daz plugin without installing the main application in poser 9? I don't use poser and it is too much expensive buy for me :-( . ..... So if I buy the two components (the main program vwd and the plugin for Daz, is it enough for using your product just and only with Daz3d and without issues? thank you.

I use windows 10 64bit and eventually I will install the updated version of Python like NolosQuinn did.

keycode17:

Yes, you can use VWD without installing it in Poser9 for DAZ Studio with the add-on DS Bridge for VWD. The DS Bridge talks to the main VWD EXE the same way Poser would, so you shouldn't have any issues.

Just to make sure we are all on the same page, you still need to purchase the main (Poser) VWD, and the DS Bridge to VWD for use with DAZ Studio. You just don't have to use Poser whatsoever, unless you want to as well.

thank you for your kind and fast answer ... I'm sure I will like a lot to test VWD, even if I'm not so advanced user ;-) . My best wishes for your work, finally I think I can afford to get the full VWD (and Daz plugin). Kisses from Italy.

.... and... It WO(ooooooh)RKS !!!!! with conforming skirt, dynamic pose, fast even with my old processor i5! After some lethal try, during I was going on without looking the PDF manual (i'm so bad, I know), with default settings, everything went flawless. I MUST say ... this program is totally intuitive even for eternal beginners like me. I can't figure so a lot of time discovering the really infinite extended options. I hope this merit of your's will give a real effective push to the Daz team for more and more better future team work. Thanks to you all.

Daremok3, thanks for verifying my reported issue. My environment is straight forward, tested systematically on simple scenes, as mentioned clearly in my issue report.

Philemot (at the Daz bridge thread) seems to have confirmed the delay-crash issue when exiting VWD and working on it so that's good...

Hair sim still doesn't work on any type of hair, custom obj or Daz classics. Frequent 'Violation error message', usually after Vertices selection stage. Quite a few similar reports about hair sim bugs too and I think VWD is close to identifying the pattern...

I'm currently using Cloth sim to animate the hair meshes which work out quite well too. VWD is usable even at this early stage. Definitely having fun with the experimenting with interesting things you can do with dynamic deformation!

There's a very energetic discussion at Daz forum about Daz users preference for conforming vs dynamic clothing and some user rendered VWD results are show cased. Lots of interest!

Hello keycode17,

I like your remark on the advanced user. In fact, I am not an advanced user myself. I own a basic version of Poser (not Pro) and I am a beginner in Daz Studio. But I love to do simulations.

I do not know if you followed the long attempt to sale VWD. I wrote some sentences to prevent the buyers to think that the use of VWD was easy. In fact, VWD is perhaps not so easy to use, It needs many tests and needs to understand the actions you make, but there is no relation with the fact to be an advanced user or not.

I will remove this sentence from the text of the program. Thank you for that.

I will remove this sentence from the text of the program. Thank you for that.

the first impact with VWD (really the first minutes) honestly was a little hard, but it was looking everything so relatively "ready to go" that I wanted to change some parameters without thinking to the result, that's it. And yes, of course I was following since the beginning the complicated attempt of your team in various forum. During some years (10!) I collected too much crap, really bad products coupled with nightmare tutorials, and it is always a rare experience when something keeps the honest promises. For us, simple Daz users, your VWD materializes the hope for what we think "autofit" (in static or dynamic pose) should be in the future. In Daz3d they had till now the best approach with business, keeping freeware the program core: it's not banal, open minded (intelligent) people are so rare today! So please go on with your GREAT effort in making Daz a 3d dream. Ciao!

keycode17:

Glad to see you are up and running with VWD, and that you are finding it intuitive to use. Have fun using it for your creations.

Mythico:

I just re-read your report that I was working from. For environment, it is your PC environment I am talking about (operating system, processors, RAM, video, etc.). As there is only a small team of testers, chances are that we might not have a variable in our PC environment that will duplicate the errors you are encountering. This is why I suggest to list your PC environment for the software authors, so if any of the beta testers can not duplicate the errors, that they might be better informed to try and track down the bugs (outside of information already on hand).

Regarding your report, I did note two things; One, I am using the shortcut "T" which opens up both Vertices Tools + Vertices Group Tabs simultaneously. Could you, please, try that work-flow, and see if the error still persists? And, two, I can confirm that if there is ever a need to force kill VWD (hung, not responding, etc.), DAZ Studio is unable to relaunch VWD through the bridge script without itself becoming hung-up, and needing to be force killed as well. Not sure if issue lies with DS, or the VWD Bridge, but I believe it does need to be investigated.

I am using a short hair model in my animation. I imported it into VWD but right before it shows me the validate button, I get this error message: "Not enough memory size, you must change the parameters." I have 16g of ram and 4g of GPU ram. I shouldn't be running out! As for the parameters, I am at a loss. I don't where to tweek it. I am assuming it is in the parameters right after I hit the first hair button but don't know what to do!

I shouldn't be running out! As for the parameters, I am at a loss. I don't where to tweek it. I am assuming it is in the parameters right after I hit the first hair button but don't know what to do!

In this case, the memory size relates to the number of springs involved in the simulation. The problem is not so much the memory in your system, but the fact that with several hundred of millions springs involved, the simulation will be to slow to be of any use. When I have this error, I'm sometime able to solve it by:

• after importing the collision and before importing the hair, I go in the bottom tab and I click on "restore default parameter"
• in the topmost tab, I click on "use spring reduction"
• then I import the hair.

Hope it helps

@agape : As said Philemot, you can use the "use spring reduction" function. You can also use the "Distance min" value. This function allows to keep only the springs that have a length higher than this value. For hair, the default distance for the springs is 0.5 and the distance min is 0.25. I suggest you to keep the 0.5 value but you can increase the distance min value to 0.4 if necessary. Some new hair at Daz are really beautiful but they have hundreds thousands vertices. When you have this message, at least 30 or 40 millions springs have been generated. This value is really the maximum value for a simulation even on a very fast computer. I want to write a mesh decimator specially made for the hair. I've began to think to how to write it, but it is not so easy. For now, you have to use the above solutions to create simulations on very high resolution hair.

(operating system, processors, RAM, video, etc.).

Win7 64bit Xeon 5670, RAM=12, SSDs only. (GPU is low relevance in VWD sim but here it is Evga TITAN Kepler updated driver).

VWD Gerald and Philemot should have noted by now another user has just reported almost exact pattern I and others are experiencing. Consistency is good.

I shall give hotkey T a try next time I run some cloth sims. Cheers...

Hello Mythico,

DaremoK3 made many tests on hair and It seems the problem comes from the self-collision checkbox. The self-collision cannot be used for the hair. In the next version, I will uncheck it and will disable it. Could you make some tests without the self-collision, please.

Make sure the hair has zero sub d on it.

Hi Writers_Block,

When you import the hair try clicking the "Use springs reduction" checkbox under "Import as".

I find that when I use "Use vertices neighbourhood" that selecting "Distance min" and increasing the value also works. On one test I had to push the distance min all the way up to 3.5 to get it to run without memory error.

It is a program limitation and not hardware related. I can assure you that no matter how much system and or GPU RAM you have you will still get memory error when using some models.

The uninstall of Python 2.7.12 and/or Python 3.5.2 (64bit) and install of Python 3.6.0a4 (64bit) appears to have fixed the problems I was experiencing. Fixed for both Poser11 and DAZ Bridge and on both editions of Windows10.

However I did get a couple of Violation errors when using Poser11 with Python 3.6.0a4(64bit) and VWD. I also received an error 13 (or 30 I don't remember which). I was doing quite a bit of experimenting within poser trying to recall how to use it and the error may relate to some sort of data cache situation. I closed Poser11 and reopened it and was then not able to reproduce the error again.

For anyone trying to use Hair simulation, and are getting the Access Violation error which is not allowing you to simulate any hair, this is possibly due to the Cloth simulation parameter Self Collision as stated by VirtualWorldDynamics above.

They both share this parameter setting, but it is not available for Hair dynamics (greyed-out). The issue lies with going from cloth simulation using self-collision, and then moving on to hair simulation (even if at a different time, or day). This is due to the INI saved state file which records, and presents the last used parameters. If self-collision was last used on a cloth simulation, then it is locked in, and when using Hair simulation you will notice the greyed-out checkbox is indeed checked when it should be unchecked. This is causing the access violation errors.

Gérald is working to rectify this for the next version (as stated above), but for now, a work-around is to before you select your Hair mesh and press the Hair button, open up the Dynamics Parameters Tab and uncheck the Self Collision checkbox. Then select your hair mesh and press the Hair button. You will see the greyed-out checkbox is now clear. Your hair simulation should now work as expected.

I hope this helps...

thanks but I was replying to another post.

Thank you for your great suggestions. I spent most of Saturday doing hair simulations on one hair model. It gave me fits! I finally decided to reduce the polys with Daz's decimator. That hair model started at 288,000 polys and choking the plugin! HUGE! I took it down to 30% and then it performed correctly!

To prevent problems with VWD, it's required to simulate one piece at a time. Not load the complete bridal wardrobe with 4 dynamic parts at once.

Start with the first layer. (hair always last) After the first piece is simulated it's wise to spawn a morph target to bake your final position into clothing or hair.

Use that vwdprop to collide the next piece on.

Will do...

Because of the hair sim bug, I've still yet to figure out what is it that the Hair sim does that the Cloth sim doesn't. Is it just the popular character's scalp pre-selected vertices presets? Is it post-simulation further vertex groups re-selection?

To me they are just meshes, conforming or plain unskinned, Hair is just another Cloth actor. So if I could use VWD Cloth sim on my Hair objects with good result, even with self-collision working on these hair-as-cloth-actors, that's ok, right?

On the self-collision note...

I know VWD is quite heroic and capable of multimillion springs, but I think it is reasonable to ask VWD users to avoid simulating hair with more than specific number of verts.

Also, remind Daz users that they do have a very useful Scene Info pane in Windows>Panes, where they could see how many tri/quad/face whatnot of individual scene objects.

Report of a few minor bugs

bug 1. After Cloth simulation, Vertices Tools. Viewport won't highlight vertices. Material group drop down, select any Mat group, will produce the follow error message.

Found a workaround today:

After the above error message, click on any other scene items loaded in the Host List, will cause Clothing vertices to be highlighted in blue and become ready for selection again.

This doesn't look like an expected behavior.

---

bug 2. During Cloth simulation, accidentally press Shift in viewport background without left clicking, caused severe crash (freeze hang).

Need to eventually Task Manager force kill to close VWD.

Daz Studio scene seems normal. Launch VWD, freeze hang crash.

Can't exit Daz Studio the normal way after that, right click task bar to exit, or Task manager force kill.

---

That's it for now....

When you forcekill VWD, you should restart the script in studio. As there is already a script running, it will be stopped.

I clicked on the custom action, which is effectively restarting the script? That caused the crash hang as stated above.

---

Anyway, I've noted the same pattern as a previously report bug.

Mythico posted at 8:07AM Mon, 12 September 2016 - #4281747

One crash pattern observed:

Sim actors can be the usual figure/prop, or both Daz primitives with sufficient vertex density.

-after dynamic simulation, press Vertices Tools + Vertices Group tab

-try to load material group = produce error message

-nothing can be done any further for this simulation session

-attempt to exit VWD = crash hang

-Task manager to force close VWD

-In DS, everything seems normal. Click on VWD action button to launch next sim session

-DS crash hang

-Task manager or Ctrl Alt Del to force close DS

---

(same as freshly reported bug no.1, which also happened after Cloth simulation)

So, this hair sim issue is also resolvedby the same workaround as the bug no.1 above:

After the above error message, click on any other scene items loaded in the Host List, will cause Clothing vertices to be highlighted in blue and become ready for selection again

---

So good news basically. Had 2 successful VWD Hair sim sessions on Genesis so far since this workaround is discovered. One is under 20K RadiantJaguar hair. One is crazy-high-poly 160K LoveMeHairGN.

I purposely reinitiated sim after a round of 30sec animated dynamic session. Did the T for Vertices Tool route, and this time, I ignore the error message, went to the Host List and click something else, I was able to continue working with vertices selection, ridigidy some more etc etc, then another round of sim without any incident.

I'll look into it. Restarting the script should really terminate the previous one. It should work better with the new version which terminates the script more efficiently. I'm just waiting for an update authorization from Rendo.

@Mythico : I would like you can use the hair import to simulate hair because this method allows to attach the hair to the head more precisely. You can use the "Nail to collision" function on the head of the character and animate your hair using this method. Like for a cloth actor.

You are right, a simulation of a cloth actor and a hair actor works with the way. There are 2 differences ;

• How the mesh is attached to the character.
• the size of the rigidification. For the hair, I use a distance which is half.

I thank you for the words I have to use for a cloth simulation. For me, These words don't correspond to a precise definition. I will use them when I will rewrite the documentation.

I will look precisely to the errors you have. I never had the problem you have with the hair selection. Have you this problem if you try to make a selection manually on the head of the character, before to click on the "Show hair vertices" button.

I will give you more informations tomorrow.

By looking at the program, I think I have found the problem. When you do the selection of the vertices on the head of the character, Are you sure you always use the good character name. When you select a character in the list, in the hair tab, many vertices, defined by a number in the HRV file, are defined as selected on the head of the character. If the character is not the right one, some vertices can have an indice higher than the number of vertices in the character. I should have done this test but it don't exist in the program. This could explain the access violation you have . I will correct this forgetting in the next version.

Could you make a test with Genesis 3 character and Import a hair using the "Genesis 3 DAZ" in the listbox.

Sorry for the delay in response. I am currently using VWD version 408.2976. I have and continue to get the french message described before almost every time I run a dynamic sim in poser 2014. I can run a static sim and it works, but then without changing anything if I try and run a dynamic one I get the error message. Using cloth I get that error about 50% of the time. Using hair I get the error 90+% of the time. Sometimes I also get the python error below:

Traceback (most recent call last): File "C:....RuntimePythonposerScriptsVWDExchangevwd.py", line 5, in modif_verts() File "C:....RuntimePythonposerScriptsVWDExchangevwd.py", line 222, in modif_verts

File "C:....RuntimePythonposerScriptsVWDExchangevwd.py", line 93, in export_verts_figure

I also have the Carrara plugin and the DAZ studio plugin. Carrara works most of the time. I have yet to get DAZ to work correctly. Your plugin goes through the calculations but the mesh is deformed, usually squished down in one axis like flattened and not in the correct positioning that the original figure was at.

Sorry I'm not more technically inclined to explain things better. But the Lecture ua-dela' de la fin de fichier error is what constantly shows up in poser for some reason. This error does not show up in DAZ studio but the mesh gets deformed. And then things work much better in Carrara but I do sometimes get that same error. And sometimes the "xxx.obj cannot be found" error message.

Thanks for the great work on these terribly missing features from all three of those products. I know the bugs will all get worked out in time. If no one else is reporting these errors I am sure it is on my part. But I have also reset to default all the attributes and it doesn't change the results.

Hello primeuser, I really would like to correct these errors.

Looking at your error messages, I see you use the Poser default folder for VWD. Sometimes, This very long path generates a problem in Poser and some users have resolved their problems by displacing VWD in a very short path.

Please, could you make a try by moving VWD directly under the C: driven, ie in a folder named C:\VWD. You can make a copy of your current VWD folder to C:, and modify your access to the program in the Poser Python interface by changing one of the buttons. If you have a problem to do so, I can send you the script to write for the button.

I wait the results of this test and I hope this modification will resolve definitively all your problems.

OK, new version has now a "Stop VWD" script to use in case of VWD crash (self crash or force kill).

Hi! First of all, thank you for creating this wonderful tool!

I have a problem rendering hair when I have more than one collision item in use. I purge the previous settings and reset the values. In my example, I am using G2F, a cape that I run through VWD before, and a shoulder-pouldron as a collision item. I use the default settings for collision items. This all loads without a problem. Then, I load the hair, also using the default settings for hair. G2F is the default selection for the collision question, so I just confirm. Then, when (in the tutorial vid) the character (in this case, G2F) should be pre-selected for the haircap-default preset, instead, it jumps to the cape, or the shoulder-poldron (depending on which I loaded last before the hair).

The default selection of the preset then happens to that item.

I can manually change to G2F and apply the preset, but then something is still wrong.

When the hair is finally loaded (all like the video, just using default settings), and I press MR to re-show the stored selection, the polygons are marked in the hair instead of the head.

This is very weird. I haven't been able to complete a sucessful hair drape, though the cloth drape works fine. I am using DAZ Studio 4.8, Win 10 and the VWD Studio bridge. I am sorry if I explained things badly, English is not my first language.

Bee

@beemeekay : I rarely make hair simulations with several collisions actors. I will redo your test and I will give you the result as soon as possible. I suppose you import all the collision objects and then the hair actor. This method is good and should work correctly. Could you make a test by importing the character, then the hair, and at the end, the other collisions objects. In all cases, I will reply you more precisely after some tests.

Okay, I'm going to test it. What I did found out is, if you have G2F as collision item first, then load the cloak as cloth, and then load the shoulder-piece, the cloak opens up the menu part for HAIR.... Much weirdness ensues. ;-)

@beemeekay : excuse me, I don't understand. You want to say that the hair menu opens when you import the shoulder-piece without pressing on the "Import hair" button. Could you make a short video showing this.

I made some tests for the hair and you can import the hair actor and the collision actors in the order you want. If you import G2F as collision actor, you have to select "Genesis2 Daz" in the listbox, then click on "Show hair vertices" and then click on "Generate springs".

I'm sorry, I can't make a video of it, I do not have recording equipment installed on the render PC. I can try screenshots, if that is of any help? The order is:

• Import G2F as collision item,
• Import cape as cloth (default),
• Import shoulder piece as collision item Then the hair menu opens instead of the collision item dialogue.

As for the other error, it's regrettable that you can't replicate it; you did use the DAZ bridge, and DS 4.8 for import? I followed the steps as shown in the tutorial video for hair that can be downloaded here on this website. I did select Genesis 2 DAZ, as the screenshot shows.

VirtualWorldDynamics posted at 9:24PM Sun, 18 September 2016 - #4283132

I will look precisely to the errors you have. I never had the problem you have with the hair selection.

Actually, the earlier hair sim bug I reported is the same as my later report of cloth sim bug no.2.

Both hair / cloth sim cases = after a round of simulation; reinitiate dynamic sim; Vertices tool; select Material group from drop down; ERROR MESSAGE; the rest of Vertices Tools remains non-responsive after closing error message. Non-responsive = vertices won't be selected nor will it turn blue.

Typically when that happens, I just end the sim session = quit VWD and restart new session. However, as stated in my last 2 posts, it's been discovered it's POSSIBLE TO WORK AROUND THE BUG = go to the Host List, randomly click on any other iterms, the Vertices Tools and Groups selection tools become responsive again, and I could continue selection and rigidification for the next round of hair/ cloth sim.

It seems the bug has to do with Vertices selection menus becoming unresponsive after a round of sim.

I hope it's clearer.

VirtualWorldDynamics posted at 9:37PM Sun, 18 September 2016 - #4283812

@beemeekay : excuse me, I don't understand. You want to say that the hair menu opens when you import the shoulder-piece without pressing on the "Import hair" button.

I can confirm this as a bug.

G2F import as collision. Default G2F free blouse Persian Full Top as Cloth. No problem so far. Click on a box prop in the Host List, HAIR PARAMETER + Vertices tools menus auto expand - without even pressing the Collision/ Cloth/ Hair button! This is of course not an expected behavior.

IF continue session without importing any more Collision actor, ignore the opened Hair menu, the session proceed as per normal with no issue. Select vert, nail to collision, rigidification, sim, etc.

IF import box as (a second) Collision actor, ignore the opened Hair Menu - select verts; nail to collision = ERROR POPUP: The selected object must be a cloth object.

More tests. Results...

Genesis 1 also has the same "highlight imported Box in Host List, Hair menu auto-expand for no reason issue".

Again, if continue session and ignore hair menu, will carry out sim session per normal.

However, I have also found, IF import 3rd object (box/other scene items) as Collision Actor, and with Hair Menu still auto-expanded, the issue can be worked arouond IF we go up to Host List, RE-select the Cloth Actor, then NO ERROR POPUP claiming "must be cloth object". Hair menu REMAINS opened/expanded btw, but the Vertices Tools selection grouping and the rest of the sim session can continue as per normal. Cloth actor will collide with BOTH collision actors.

---

It's good that the 'Hair Menu Auto-expand at 2nd Collision Actor Import" is not a big bug and can be bypassed. In any case, this still has to be fixed. Because

• Highlighting a 3rd object in the Host List should not auto-expand Hair menu.

• The Hair menu should not remained opened in a multiple Collision actors session for no reason.

---

So far, it seems most of the "bugs" I've come across can easily be resolved by making VWD auto-selecting (or auto-REselecting) the Cloth or Hair object in the Host List, when users click on Vertices Tools at any point of the session.

@beemeekay and @Mythico : I want to be sure to understand your problem. I made a short video showing the workflow you use. Can you confirm that you would have a problem on your computer using the same actions. https://drive.google.com/open?id=0B9c39Rz2Ec-JMUN4OHJmbkp5bWs

Correct. Hair menu will open as soon as I click on the next item in Host List. (Win 7 64bit DS 4.9.2.7. Latest DS bridge installed )

Yes, that is also the steps that cause the hair menu to show up.

please, allow me to say... I love you guys .. since the last VWD plugin fix, I am a lot more involved with my Daz hobby (hair dynamic). And of course, thanks to the users in this forum, for making less sharp our learning curve. Go on like this!

@Keycode17: thank you for your review. By rereading it, I realize that I have answered you as someone who is overwhelmed and I apologize for this. Sometimes I feel I cannot answer at all. The hair simulations also are also my favorite ones. I am happy you use VWD to make hair simulations you want.

Hi,

I have been using VWD successfully for weeks and done many sucessful simulations. It has been great fun. I've hit a problem that is incredibly simple, and I'm sure it never used to happen, but now I can't get rid of it. I am modelling V4 in a gown sitting on a bench. V4 and the bench are collision objects, and I use 100 timesteps to go from default pose to sitting. The dress always intersects the bench. It is as if the bench is not there (although I can see it in VWD Scene Viewer).

I set all parameters to default. It still does it. I have added a picture of the sim half-way through to show that the dress is not in any way deflected by the bench.

Help :-)

Hello valkeerie, I suppose the bench has a very large mesh structure. You can resolve this problem by using the subdivision fonction on the bench with a value of 1 or 1.5. I hope this solution will resolve your problem.

Hi VWD, thank you for your prompt suggestion. It took me a lot of trial and error but I was able to resolve the issue by using a subdivision value of 0.5. Even at 1 interpenetration was still occuring. I have attached a screen capture of the complete animation (for the benefit of future readers). Getting cloth to drape well is hard, but I am satisfied - it is 1000 times better than anything I could achieve with morphs.

I may have uncovered a simple bug. The check boxes "use animation" and "Subdivide" are mutually exclusive. If I import the stone bench after V4, and select "Subdivide", it clears the animation checkbox and animation for the figure does not occur. If I import the bench first, and then V4, I can click "use animation" for V4, and dynamic simulation then works as intended. I lost many hours discovering that.

VWD is brilliant and it has radically changed the way I work in DAZ. Even with cloths that fit well I do a quick static simulation and it makes an enormous difference to the appearance.

Thanks Valkeerie

.

Hello Valkeerie,

I am happy you found the solution.

For the importation, you are right the checkbox "subdivide" unchecks the checkbox "Use animation". The reason is that if I import the animation for this element, the subdivision can be different at each frame (not the same number of vertices). The "Subdivide" checkbox must be used only for static collision element (as the bench).

Nevertheless, you can import the collision elements in the order you want. You just have to check the "Use animation" checkbox for the character. I have to give more informations in the documentation.

Have a great day.

  Gérald

Hi, I hope I'm posting this in the right spot...I just bought the plug in for Poser and the Bridge to DS. I'm having a lot of fun with static simulations but I'm finding that when I try and do a dynamic simulation VWD crashes. This is most likely user error as I'm still trying to work out the process so I'm hoping someone can point me in the direction of a simple tutorial for the DS bridge? At the moment I'm loading and setting up the timeline in DS. Putting the timeline back to the start in zero position and then opening VWD, then I'm showing the host. I set up Dawn as the collison and the clothing as the cloth and then starting the simulation. Is there something I'm missing?

Hi pen,

I'm not sure if the bridge would be the issue, but I never tested for Dawn (or Dusk), so I could not verify if this could be a causation.

Is VWD locking up (not responding) when you run the dynamic simulation, and you have to force kill it through Task Manager?

This happens for me for only one figure I tested and use; SM G2 Olivia.

I believe it might be some kind of rigging anomaly error that isn't accounted for, or at least possibly the case in my account. Static sims with G2 Olivia are fine, and both static and dynamic sims are fine with G2 Jessi, but animated sims for Olivia with same clothes that work on Jessi fail ten out of ten times without exception.

Try this for a test; Load in your animated scene as you have before, but do not press the Dynamic Simulation button. Instead, cycle through the animation one frame at a time (right arrow key) all the way to the end to see if the animation data is intact. For me, the animation plays through to the end one frame at a time, but fails (locks up) the second I press the dynamic sim button.

I have been using a long-about technique of simulating each frame independently with static simulation, and dynamic deformation (holding SHIFT key) while cycling through all frames to the end. Not so bad for 30 frames to achieve a draped pose, but not for an animation or anything longer.

If Dawn is failing like Olivia, I believe these figures might need to be looked into as how VWD is using them with animation.

Hi DaremoK3, thanks for the info...I'll give it a try tomorrow. It sounds like it may pay to try doing it with Genesis3 and see what happens. If that works then it is possible that it could be something like you've mentioned. I'll see how I go...thanks for the help.

So I gave it a try with Genesis 3Female and a simple dress...dynamic simulation seemed to work but when I sent it to the host the dress disappeared.

I may have to give your technique of multiple static simulations...I'm not animating I just want a draped pose.

pendraia:

Well, that is good that you were able to accomplish an animated drape with G3, but sucks that it failed sending to host. Did you try to send back a static pose, or the animation which contains every pose from every frame?

Send Pose to Host usually works on a consistent basis for me, and I usually send many poses to host per VWD session. Maybe try some smaller tests to rule out variables regarding VWD, the DS Bridge, and your PC environment. Some software don't like some setups, but I highly doubt this is the issue.

What are the settings you were using with the dress, and also what is the vertex count?

You can check the vertex count in DS, or inside of VWD by going into the Vertices Tools Tab (shortcut key T), and selecting the "INV" (invert) button. It will select all vertices and display the count at bottom right of screen.

Also, you have one more option to achieve your draped pose with VWD and DS. You can run the animated drape in DS only with conforming clothes, and then send both the collision figure and the cloth object in their posed states to VWD (on the last frame). Then you run a static sim to complete the draping which you can control by the rigidity settings. If you are using a dynamic cloth you will have to turn it into conforming first for this to work. I do this with my static dynamic clothes created in Marvelous Designer.

The trick here is to have your animation tab open, and after you launch VWD and then populate the Scene Import Tab with the Host List, VWD will resort back to the first frame. Just press the skip to end frame button, and you will be able to load in the collision objects and cloth objects in the posed state on the last frame. Make sure you do this before loading in either mesh objects or you will get first frame posing only.

Below is a WIP image I am working on that employs both techniques. The figure on the left is a 30 frame animated sim, and the figure on the right is a static drape utilizing the technique described above. Notice the drapes on the Hakama pants for each figure. Both are the same meshes, but are draped with very different settings. I wanted a stiffer, heavier cloth while managing the pleats on the left, and a lighter, flowing cloth on the right, but still be able to maintain stiff pleating. For the one on the right I added a pleats material zone inside of DS that allowed me to set high rigidity on them while keeping the rest of the cloth soft and springy.

And this image shows the setup for the stiff pleats using by neighborhood rigidification:

Thanks for the info...it will take me a while to digest it I'm afraid and try it all out. VortigensBane has provided me with a list of tutorials also over at Hivewire and expained where to find the pdf file so I will be checking all that out also. I'm tending to think most of my problem is user error because I don't really know what I'm doing but I will try out your suggestions as soon as I get chance. I start back at work tomorrow so it may take me a while to work my way through. VB also said that decimating stuff helps some times so I'm going to give that a try also and see if it helps. Thanks again for all the help...

Hello pendraia,

The documentation is not very userfriendly. WimVDB is writing a new documentation which will be very well made. It will be very helpful for you. We have to improved it for Carrara and Daz Studio. Some parts are a bit different from Poser.

Despite all the help given by DaremoK3, Tell me if I can help you. I want to make VWD easier to use and more stable. Feel free to send me the actors with which you work and have issues. If I own them, I can make some tests to solve your problems.

I currently correct some bugs and the next version will have some new functions and will allow to restart a simulation without (really) leaving the program.

Thanks VWD...I'm really enjoying using it and I think at this point many of the issues I have might be lack of knowledge on my part. DaremoK3 and VortigensBane(over at Hivewire) have been really supportive at the moment I just need to get to work on watching the videos and reading the pdf file that VB mentioned. Once I've done that if I still am unsure I'll be in touch. Glad to hear that you are doing more work on the documentation because I think that will help a lot. I'm willing to work through finding solutions if it does turn out to be a bug and I will get in touch if that is the case.

I didn't know that I could send a static pose for a dynamic simulation so I sent using the button for the dynamic simulation.

Send Pose to Host usually works on a consistent basis for me, and I usually send many poses to host per VWD session. Maybe try some smaller tests to rule out variables regarding VWD, the DS Bridge, and your PC environment. Some software don't like some setups, but I highly doubt this is the issue.

That's what I do when I'm doing a static simulation. At the moment I'm trying to stick to using simple objects for the draping...and I've learnt now that I can have more than one collision item which may have been obvious but took me a while to catch onto.

What are the settings you were using with the dress, and also what is the vertex count?

I'm still tending to use default settings except for Gravity as that tends to pull things down when using the default so I tend to lower the gravity. Sorry I didn't look at the vertex count. I will do better next time. I think I need to start taking notes in OneNote and get more serious about this...

You can check the vertex count in DS, or inside of VWD by going into the Vertices Tools Tab (shortcut key T), and selecting the "INV" (invert) button. It will select all vertices and display the count at bottom right of screen.

Thanks...I didn't know this.

I'm not quite sure what you mean by this but once I've watched some of the videos it might start to make sense.

Just press the skip to end frame button, and you will be able to load in the collision objects and cloth objects in the posed state on the last frame.

This looks amazing...again, thanks for the help.

I bought VWD and the DAZ Bridge a few days ago and, after an initial problem with loading the wrong version, I've tried maybe six simulations. Of those six, four have crashed DAZ Studio. I am trying with a Genesis 3 figure and have tried V4, G2F and G3F clothing items. All have crashed DAZ Studio at least once. I've shared the specs of my PC in another thread (yesterday, in the DAZ Bridge thread) but be in no doubt that I have a decent PC with a recent i7 Skylake, 32GB RAM and a GTX 1070 GPU.

I know from other users that I should expect the occasional crash but this many is making the product impossible to use.

Hello Marble,

I use the program and the bridge several times by day and I regularly have many days without any crashes. I regularly use V4 or G3F with many clothes and hair. Could you tell me if the crash comes from Daz Studio or from VWD itself. What is the folder in which you've installed VWD?

That's what I don't know. I'm following the Biscuits video for the parameters but it usually crashes before I get to the parameters. Just when I import the dress as cloth I get a message on screen saying DAZ Studio has stopped working.

On the optimistic side, I have tried four more since I posted the above message an no crashes. I have started deleting the exchange files before I do anything else so perhaps that has made a difference?

This is from the DAZ log file:

Yes, it's linked to the exchange files. According to the log, the first file from VWD the bridge encounters is a termination order, probably a left over from a former execution. Afterwards, the bridge is ending cleanly and I don't understand why studio is shutting down 5 seconds later... I recall this error from early in the beta version, but it's been corrected since. Are you sure you're using the current version of the script ?

This is the DAZ Studio plugin info:

I have an interesting bug; rendering after posing hair, the render is a blank image, as though the camera was under the ground plane for example; make the VWD posed hair invisible, and it renders - obviously with the exception of the hair. I've not had the same happen with clothes.

I've been running VWD with Daz Bridge for a while now and had no problems. I've just started to get an error "the file nom_objects.txt does not exist". I've reinstalled both VWD and the bridge, but I'm still getting the same error message. I'm running daz 4.9 64bit. One thing I've noticed - I'm using the 64bit dll, but in task manager it's showing as "VWDCothAndHair.exe (32 bit)"
I'm using VWD version 1.0.518.3626
