@thehawkman : if you want, you can replace one line of the file "mainButtons.py" which is the default interface for Python. The line "poser.DefineScriptButton(9, ":Runtime:Python:poserScripts:VWD:VWDButtons.py", "VWD")" will replace the 9th button by the text "VWD". By pressing this button, you will execute the script "VWDButtons.py" which displays the VWD buttons. The path have to correspond to your VWD installation, This example corresponds to the default installation.

@Smaker1 : Thank you, I cross my fingers even if this is not really easy for writing program enhancements ;-)).

Now there are 3 tasks to do :

• enhance the documentation. That's me who is a bit late.
• make a new release which definitively correct the Python errors (Thanks to Wimvdb) and which makes some enhancements.
• make some video tutorials (not with the same quality than those of Biscuits) but more technical, to explain the functionning of VWD.

@Fivecat: great! when I see your hair simulations (as those made by Biscuit) I want to improve mine.

After loosing a real big project (I'm so stupid sometimes) I had to find a simpler one. Genesis 3, Dancing slip from J. Cade simulated with VWD. Lois Greenfield inspired. I love dance picture!

What a beautiful sim and render, Smaker1!

Is friction working? I don't see any difference changing it or switching it on or off.

The animation in VWD is different than the animation in Poser, if I "change" elastic value. In VWD it looks fine and in Poser the animation arrives unmodified without elastic value.

@honzu : The friction works correctly but it is not strong enough, I want to improve it. I don't understand how the animation in VWD could be different from the animation in Poser because VWD generates a cache file which is sent to Poser. Could you send me two images, one from VWD and one from Poser that will show me the differences.

@wimvdb : Thank you for your rendering. I love to see realistic renderings of hair. This has certainly been the main reason of the development of VWD. Thank you also for all your help.

@fivecat : thank you for these two renderings using marvelous Adora hair by Biscuits. In the current release, the wind is only defined by a vector and the direction is not easy to find. In the next release, the wind will be defined by an arrow on the screen making the positionning easier.

It now works fine, if I do it in the right order. Like static simulation I was pressing <escape> while animation calculation, then changing parameters and then continuing the animation calculation. This way it looks good in VWD and different in Poser.

"if you want, you can replace one line of the file "mainButtons.py" which is the default interface for Python. The line "poser.DefineScriptButton(9, ":Runtime:Python:poserScripts:VWD:VWDButtons.py", "VWD")" will replace the 9th button by the text "VWD". By pressing this button, you will execute the script "VWDButtons.py" which displays the VWD buttons. The path have to correspond to your VWD installation, This example corresponds to the default installation."

Either I am misunderstanding the installation instructions for the main VWD program or something else is wrong. My VWD demo is installed at "C:toolsHome & HobbyVirtual World Dynamics Cloth and Hair Simulation" and therefore the code I added to the main.py file is

poser.DefineScriptButton(9, "C:toolsHome & HobbyVirtual World Dynamics Cloth and Hair SimulationRuntimePythonposerScriptsVWDVWDButtons.py", "VWD")

The problem is I get an error message: Null or empty script name passed to PEPythonEngine::DoScript()

I take it that means my path to VWDButtons.py is incorrect but it can't be, I've checked. I am surprised that no one has made this complaint before about Poser not saving the settings for the Script Palette (don't know what genius thought it was a good idea to silently revert the settings) but I think there is a need for a better way to add VWD to the Script palette (or better yet have it create its own Poser window).

You forgot the all important colons ( : ) in your address. They are universal folder separations replacing forward/backward slashes. The python error is because python is reading the whole thing as the name of the script, but unable to actually locate it.

I did this for the demo, and put it in the number one spot. It works, and it stays. Available every time I open up Poser. Hope this helps...

I already figured it couldn't find the script. The problem is that it should. You say it's missing the semicolons. Those only seem to be used when the script is found in the main Poser runtime. How do you explain that number 10 works without semicolons? Goddamnit this forum is terrible. Coming back to check for replies I just noticed that the forum stripped the slashes from my path. JFC that is not how you avoid getting hacked. I'm not even a programmer and I can tell this is below amateur coding.

My apologies, thehawkman, I was making assumptions.

I thought there might have been a chance the forum had stripped your path markers, but I didn't realize your version was utilizing forward slashes. I thought colons (not semi-colons) had replaced the slashing pathways since the discovery years ago that helped with universal compatibility. Mine are all colons in Poser 9 on Windows XP, so it might be environmental. I haven't checked on my PoserPro2014 on my Windows7 box, but I suspect it is the same.

What is your operating environment?

Also, there is a possibility that Python does not like something in your address pathway. I am not sure, but the "&" in the address might cause an error.

Could you, please, transfer the "VWD" folder into your Poser scripts folder, and try from there just to see if you can get it working at least. If it works there, then you will know that Python does not like your original address. Barring this, I would be stumped to your issue, and if you can't get it sorted, maybe VirtualWorldDynamics will help you out further.

Here is a pic showing it always there for me, and the python coding with addressing (notice the colons?):

Hope this helps...

Issues uploading images...

Here is the other image:

@thehawkman : I made some tests and I think it is better to have a shorter path, like the one gave by DaremoK3. Personally, I use a very short path "C:VWD". The Python script works correctly now?

I would love to buy the full version of this but ouch man, $65 and coupons don't work on it. That's waaaay too steep for me.

@JohnDoe641 : I activate the coupons.

@JohnDoe641 : I can't activate the coupons, Sorry. I will ask how I can reactivate them.

The coupons are reactivated.

VirtualWorldDynamics:

What coupons, and how can we receive/use them?

It appears VWD Cloth And Hair is not on sale, so how does this work (coupon/discount)?

Somebody already working on a port to Mac OS X? If not please drop me a PM.

@DaremoK3 : In fact, I am not able to give you explanations about the functionning of the coupons. I just ask to Jenn if she could give me some infos. You tell that VWD is not on sale, have you had a problem for buying it?

@Nagra_00_ : Currently, someone works on the possibility to make VWD working on Mac. I wait for last tests and I could give more informations soon.

I will send a new version at the beginning of May. This version corrects definitively all the Python naming problems. It allows to make an easier positionning of the wind. It also corrects some bugs.

My next work will be to make some video tutorials with the help of TomYee who certainly will correct my poor English and will speak in the videos. If anyone has ideas on Tutorials which would help to understand VWD, all the propositions are welcome. I will make these tutorials.

During this period, I will begin to work on a version that will allow to make simulation trials without the constraint to close and reopen the program. I have found all the memory problems which made this possibility impossible before and all is ready now for making this modification.

First: I admit I did not read this thread in full, so I might be asking redundant question below. Second: I downloaded the demo, watched the excellent Biscuit videos for clothing. Third: I loaded V4 with a simple dress and executed the program with good results. Fourth: I watched the video tutorials for hair. I see that it is complicated, but doable. I didn't try it.

Question: is the subject of Poser strand hair relevant? Does this program work with it?

Fifth, I don't think $65 is too much for this technology.

[EDITED: I just saw examples for dynamic hair on page 8 of this thread. Thanks Biscuits]

I am buying this program.

::::: Opera :::::

Hmmm..

Maybe not?

When I load a dynamic hair model onto V4, the skull cap shows up in the PoserList, but not the strands.

So, I guess I'm renewing my question: is dynamic (strand) hair supported?

Thanks,

::::: Opera :::::

VirtualWorldDynamics:

There seems to be a little bit of a language barrier, so I understand it might be a little difficult for you to understand the written context. I know English is not your first language, so please bear with me.

I am a potential customer of yours. More so, I am almost 100% a customer of yours, but I have not yet purchased only because I do not currently have $65.00 U.S. I have been saving up for several months, but I am not quite there yet. I should be able to purchase in one to two weeks. You have no idea how big of a deal it is for me to make any kind of purchase (no income). I picked your software to purchase because I want to support your work, and because it is a viable alternative for Poser dynamics, and possibly DAZ Studio in the future (which I am also planning to purchase if made available).

I have been watching your development since the beginning, last year, and you have created a wonderful product. Adding the dynamic pulling ability is what really sold me on VWD. Something that is severely lacking in Poser's native cloth sim, and what I am used to using in my workflow with Marvelous Designer.

Okay, let me try to answer your questions in your last post that are pertaining to my original questions that I asked you regarding coupons, and the purchasing of VWD.

1. No, I have not had any issues trying to purchase VWD, because I have not yet attempted to purchase VWD (Don't have $65.00).
2. VWD is listed in the store at full price of $65.00. Hence, not "on sale", or showing at a sale/discounted price.
3. You mentioned coupons for this product, but your customers (at least myself) do not know in what capacity you are mentioning them for. Renderosity is notorious for NOT allowing coupons to be used on any SOFTWARE in the store. So, maybe, now, you can see my confusion, and need to ask you to clarify your statements regarding coupons.

If I have to purchase at full price, then no worries, I will pay full price, but have to wait a couple of weeks for an odd job to provide me with the necessary money to make my purchase. If I could use a coupon, and get the product at a discount right now, then I might have the ability to purchase right now, provided the final discount equals the amount of cash I have on hand. If I have to wait, I'll wait (and you'll get the full payment). Just looking for clarification...

operaguy:

No, it does not work on dynamic hair strands. Only on conforming mesh hair.

[DaremoK3]

No, it does not work on dynamic hair strands. Only on conforming mesh hair.

Thanks for the information. I'm running a sim on the prop Wild Hair right now. Will post results.

[@operaguy : VWD is not able to animate dynamic hair strands. Personnaly, I don't use this kind of hair. Their simulations are very fast, their renderings can be beautiful, but the rendering time is too long. The animation of conforming hair gives good results with a computing time and a rendering time not long at all.

@DaremoK3 : About the coupons, I don't know at all how they work. Jenn gives me a reply but, for my poor commercial competence, it is not clear. I can give you all the technical replies you want, but not commercial replies. Please help!! if someone can give us explanations about the coupons we are both interested. I took just a little time to make this reply. Tomorrow, I will send you a PM.

I have started a thread in the Community forum HERE If any of you want a forum solely for VWD, please chime in on that thread. Thank you & have fun!

@3DFineries : I don't know if all is ready for that (people and program). If this forum is not made, I would like to create severals threads which will explain the different parts of the program to avoid to continue a thread which becomes fully unreadable. Thank you for this proposal.

@DaremoK3 : I sent you a Renderosity mail

@ VirtualWorldDynamics, OK, I've waited and waited for you to get back to me so I can discuss some of the issues with translating your user guide. Please let me know whether you want me to continue; if so, I really need feedback. Please understand, I realise that things must be very hectic for you right now (btw, congrats on finally getting Renderosity to realise the value of your program and finally listing it for sale). If you want me to wait for a while and let you get your May update completed; that's fine - jlmk. If you want to translate the user guide using someone else's help (someone who is fluent in both French and English, for example), that's fine; I won't be offended or anything (I know my help translating isn't great but it's here all the same) - I'd just like to see VWD Cloth and Hair do well for you................

Can someone tell me; I have 2 items that need to be collision actors (V4 and a top with a raised collar and no "cling wrapping" around the breasts so hair can't fall in the cleavage area), but VWD only allows me one (I selected both V4 and her top and I get the "Validate" dialogue where I have to choose which one is the collision actor). How do I get around this limitation?

@Erwin0265 : I will give you informations about the documentation. I want just to send my next version in May. Then I will be quieter. If you have imported two collision objects in VWD and want to apply hair, The two objects will be applied as collision object on the hair. VWD asks a question to know what will be the actor on which the hair has to be linked. This actor is always the main character, in your case Victoria4. Remember that the free edges of the collision shirt must be removed from the simulation.

I think that having a specific forum for VWD would be a good thing. We have to convince Renderosity that this forum is very useful. To do so, many people must tell they need this forum. I ask to all the buyers and all the persons who have set VWD in their wishlist, to go on the link gave by 3DFineries at the top of this page and write a message in this thread to say that this forum would have to be created. This thread has been very useful at the beginning of the development of VWD. Now, it is too large and needs to be cut in smaller parts. Creating a forum for VWD will allow to help you more easily and will help you to find a particular answer concerning the program. I count on you.

@VirtualWorldDynamics; "I want just to send my next version in May. " - thought that might be the case - no problem; I'm not in a hurry to do lots of work.... "Remember that the free edges of the collision shirt must be removed from the simulation." The shirt I am using hasn't been through a simulation as it fits my character perfectly. Do I still need to remove the free edges and if so, how - as it hasn't been through a simulation? Thanks

I've been experimenting and learning the first-level skills for this plugin. I'm to the point of being able to simulate both hair and cloth in one animation. It's pretty exciting, because many issues with the PoserRooms approach are gone, especially one mesh respecting the space of another!

The investment of $65 was not the big thing for me, with regard to commitment for this approach: it is the learning curve. I have gone far enough in to believe that a full plunge into the controls would yield a valuable tool for animation.

There's still a lot to learn. For instance, this animation has jitter. I am sure it is due to a setting. Something is set too aggressively. Before I use trial and error, can you give your best guess where I should look?

Animation 8MB

Any comments and advice would be appreciated...

::::: Opera :::::

@operaguy : Your video is really superb. I love the fluidity of the dress and the hair. There are some instabilities near the ears of the character. When we begin a hair simulation, it is impossible to know how the hair will behave near the ears. Some hair behaves correctly an other ones not at all. You can reduct these instabilities by removing the ears from the simulation (no collide for current collision). You can also increase the collision distance on the hair vertices near the ears.

@All : The simulation, sent by operaguy, shows that it is not possible to make a "two click" software for this kind of simulation. VWD allows to work with clothes and hair which have never been designed for simulation. It is possible to animate these clothes and this hair, but It will NEVER be possible to simulate them without understand the problem you have to solve. It is for this reason, I want to create video tutorials. It is for this reason, a forum for VWD is necessary. If you want to work with VWD by understanding how to realize great simulations, PLEASE, send a reply in the thread opened by 3DFineries. Operaguy, I thank you for this video.

@VirtualWorldDynamics

Okay, I will fuss with removing the ears from the simulation and increasing the collision distance. The hair model is Wild Hair.

The tutorials by Biscuits were fine. I like her pace. I had to watch them many times, pause, then go slowly step by step.

Now I'll look for that thread by 3DFineries

Excuse me, I was not sure that my message has been sent.

How do i exclude just the ears of V4 from collision? I only know how to include the entirety of her mesh.

@operaguy : You have to select the character in the listbox in the "Scene import" tab, select the ears on the character and click on the "No collide for current collision" button. Could you tell me the exact name of this hair, I haven't found it.

Ok, I'll try that. I see the button.

Wild Hair. I don't think it is a live product any more.

link to the hair

@VirtualWorldDynamics; What about my question? You went on to answer Operaguy's questions and forgot about me (sob, sob....) So, just repeating my question:- "I want just to send my next version in May. " - thought that might be the case - no problem; I'm not in a hurry to do lots of work....? "Remember that the free edges of the collision shirt must be removed from the simulation." The shirt I am using hasn't been through a simulation as it fits my character perfectly. Do I still need to remove the free edges and if so, how - as it hasn't been through a simulation? Thanks

@Erwin, Excuse me, I wanted to reply you in my last message. I suppose the simulation of the shirt is good and you want to apply hair on the character and the shirt. When you make the simulation of the hair, you have to import the character and the shirt as collision objects. The shirt have free edges. The vertices placed on these edges of the mesh have normals which are computed using the average of adjacent faces. These normals are generally different of its neighbor normals. This can generate instabilities because the hair may be repelled by two normals having a great angle between them, depending on the position of the closest normal when the hair moves. There is another solution if the shirt is everywhere close to the character. Generally, the shirt is repelled at a distance of 0.2 from the character. You can apply a collision distance of 0.4 or more to the hair vertices which can collide with the shirt. In this case, you have just to import the character as collision object.

OK, thanks; I'll have a play............

I gave up on the hair model Wild Hair. I could not get rid of jitter. To prove it was just the model and not the plugin or "me," I acquired Becca Hair, with which Biscuits has made a fine video. This worked instantly.

I am thrilled over the end of the nightmare of the Poser hair/cloth room and it's collision failures. Adios.

Here's the video:

Click for V4 with Becca Hair

@operaguy : Thank you for your video, I love the fluidity of the cloth and the hair. Becca hair gives directly very good results. I tried to find the hair you used before but it is not available. I made many tests with hair and some hair give bad results they always have some instabilities. Studying these hair, I see they have vertices inside the head of the character. This always generates instabilities. The solution is to make a first static simulation by removing the gravity and the Inertia. Let the simulation running one second. Send the results to Poser. Rename the hair because the Hair_name_VWD will not usable as dynamic element. For example, replace the MyHair_VWD by MyHair_New. Then restart VWD and restart a dynamic simulation. The first simulation will repel the vertices outside the head of the character without changing the shape of the hair, the second simulation will make a simulation with correct hair. I want to make a video tutorial showing how to resolve this kind of problem. Thank you again for this example @operaguy, this shows that VWD will give you all the tools to create all the simulations you want. It never will do them by pressing two buttons.

I use this example to say again that a lonely forum will be the best way to explain how to make complex simulations. Some buyers have sent a reply to the message written by @3DFineries at the top of this page. There are 80 persons who have set VWD in their whishlist. I suppose these persons want to use VWD to make complex simulations. Many questions ask their own thread. If you think that decomposing the questions is a good solution to explain VWD, PLEASE, reply to this message.

Ok, so I managed my way through a few simple hair animations. The software works very well!

After the the sim. was done, I sent it over to Poser (PP2014 in my case) and I thought of exporting the simulated hair (final frame in my example) for a later re-use. Doing so, that I don't have to animate all again, in the future. I exported the (VWD animated) hair with different options, but always, when loading the exported hair back as a morph target, into the original hair, it "explodes". Just like when the vertex order has changed. Is there a good practice, of exporting the simulated hair as a morph target, so it can be re-use later again?

@ErickL88 : Thank you for your purchase. I would like to understand your problem. You make a simulation in VWD, all works well and you can see the simulation in Poser? If this is correct, I can explain you why you cannot be sure to use the deformed hair as morph target. When I began to develop VWD, I made the simulation and then, I applied the Poser cloth modifier to be able to use the .DYN file to animate these dynamic elements. Some of these actors returned with a false vertices count and the simulation was unusable. To correct this problem, I apply the Poser cloth modifier before the simulation. The animations in Poser are fine, but the original mesh and the simulated one have not the same vertices count. Then, you cannot apply it as morph target. The best solution would be to not apply the Poser cloth modifier. This is perhaps possible in Poser 11 which uses a .ABC file for simulation. I have to make some tests. But this solution is not possible for your current version. Have you this problem with many hair?

I thought to send a new version today, but I want to ask to Jenn how to proceed. This new version will be available tomorrow, I think. In fact, there is no only one version but two versions. A complete version like now and a lite version which returns only static poses to Poser, not animations. This lite version will have the same functionnalities than the complete version, but the "Send animation to Host" button is not enabled. This Lite version will be at 45 Dollars. This new version have some improvements, The wind is easier to use, the static simulation is more precise, you can see the stress of the cloth or the hair. This version will be compatible with Carrara and Daz Studio by using the Bridges developped by Philemot.

Hello, I did a hair sim using V4 and S3P Sassy Hair. The sim was over 2200 frames and hair worked fine. However, every sim using same character and hair, less frames and slightly different anim, the hair bounces, jumps randomly. I have deleted files, rebooted, changed softness, increased/decreased number of vertices but the hair continues to jump. I have posted a short Video. Also, how do I keep the hair from falling, stretching as you can also see in the video.

Thanks for help.

@NolosQuinn : Some hair have stresses and bounces. As I said in a precedent message, it is impossible to know if hair will move correctly or not because a big part of the mesh is hidden. If some hair vertices are inside the head when you import the hair, necessary, there will be instabilities. you have to make a first simulation to repel these vertices outside the head and save this new hair for next simulations. I am sure I have Sassy hair and I will make some tests tomorrow and I will give you the results. I want to make a video on this subject.

@NolosQuinn : I did a test with Sassy hair and everything seems to run correctly. You say you have an animation that works well and others that do not work. Is it just the animation that is different or have you applied different morphs on Sassy hair. Normally, if the hair is the same and in the same location on the character, all simulations should work the same way. If the hair are different, There certainly are vertices inside V4's head. I can explain you how to resolve the problem.
