that's one sweet flip you've got going there. nice work!

The hair styling took is looking very promising. I am very excited about it. Thank you for your hard work on this.

Take care of yourself first. The hair room will still be there when you're up to it.

I'm fine now.  No worries.  Whatever it was just had me messed up on Sunday.

The two hair-positioning methods shown above can be useful for certain sorts of things, but after trying to use them to make something, I realize a method is needed to sweep the selected hairs more directly along the path.  I'm trying to work out something which will allow one to place the markers around the surface of the parent object (or anything underneath the hair) and have the hairs end up following that path.  As close to drawing the hair path directly around an object as might be possible in Poser.  Or such is my hope, at least.

This involves the predictable conceptual problems as I try to work out how to implement it.  :unsure:  So my big problem today is just trying to re-space the vertices of the hairs properly after I've redefined the endpoint of the hair.  I'm still overlooking something which is key to achieving this.  Grumble.

But I'm really fine, otherwise.

Thanks for the comments, jancory and NanetteTredoux.  I hope I can get something together which will be useful and fairly accessible.  I don't want something which is as awkward as the existing tools, just in a different way.  :lol:

I've always thought the hair room needed a comb or a brush tool.

Now I need to add the handling by hair group and after that I need to tweak a few things and build the Tk GUI for Posers 7 and below.  So we're moving along at a decent pace.  :laugh:

Oh that last feature will be ideal for making a comb-over!

And Bald Vickies everywhere sang Hallelujah!! :tt2:

The results can be a bit cleaner, without all that... dang, what's the word?  Fringing?, if the hair selection or hair group is defined more carefully.  I just applied the function to all hairs in a group which was set up more-or-less at random.  It seems evident that careful design of the underlying hair group prop and its group divisions is the key to getting decent results with any hair-design tools.

One problem I do note is that the "Y locks" aren't being defined very effectively on a more complex prop like the Sydney scalp prop.  The shaping propcess works fine for the locks, but they're broken up into smaller pieces than I'd like, making them hard to use for selection.

You should be able to run this on any grouped object.  It should grow the guidehairs for you if they don't already exist.  Then start adding markers to the scene and you're ready to start shaping the hair using the marker path.

I'll be working on trying to improve things for a bit yet, so if anyone finds a bug or problem, please let me know so I can try to fix it.

I'm trying the hair script that youposted on the 1st and I get this message reaptedly until I hit end script:

Traceback (most recent call last):  File "G:Program FilesSmith MicroPoser 8RuntimePythonposerScriptsScriptsMenuhair_to_path5b.py", line 3143, in timed_preview    self.preview_path()  File "G:Program FilesSmith MicroPoser 8RuntimePythonposerScriptsScriptsMenuhair_to_path5b.py", line 3162, in preview_path    self.marker_positions.append((xt,yt,zt))AttributeError: append

I will admit I have no idea what  I'm doing. I ran the script, clicked on a hair group, selected hairs, selected y locks, hit start preveiw and got the message. I tried just clicking on a group and it happened. I'm using p8. is this script for 8? Am I doing something wrong?

Have you added any path markers to the scene?

Looking at that part of the code, I can sort of see how it might get confused, but I can't get it to happen.  I'm using Poser 8, myself.  The script should support all versions of Poser greater than 5.

So you're not doing anything wrong, as far as I know.  You've just found the first bug which I hadn't noticed.

Is this problem recurring?

I did add path markers in some of my tries. The new script seemed to work ok on the brief try I gave before work this morning, at least it didn't give me an error when I clicked the preveiw button. I'll work more with it after wrok today. I'm really excited about this script.Thank you for making it.

I hope it works for you!  I apologize for the error.  The most frustrating errors to de-bug are those which don't affect you, the programmer, but affect others.  I do know there are a couple of other things that can go wrong, but I haven't been able to re-create them for de-bugging.  :sad:

If you work with the script and have any thoughts on how it handles, let me know.  I'm not convinced that all features are as flexible or accessible as I'd like.

In my attempt to make some hair, sometimes when I try to select a a group I get this error

Traceback (most recent call last):  File "G:Program FilesSmith MicroPoser 8RuntimePythonposerScriptsScriptsMenuhair_to_path5b2.py", line 3055, in fill_hairboxes    result = self.stylist.get_hairprop(grp)  File "G:Program FilesSmith MicroPoser 8RuntimePythonposerScriptsScriptsMenuhair_to_path5b2.py", line 184, in get_hairprop    self.restore_roots()  File "G:Program FilesSmith MicroPoser 8RuntimePythonposerScriptsScriptsMenuhair_to_path5b2.py", line 256, in restore_roots    verts = geom.Polygon(hi).Vertices()poser.error: Invalid Polygon index

It doesn't do it on all the groups just some of them. I can send you the prop if you want it's possible that certain conditions of props will cause the errors I suppose.

Belated birthday greetings to this thread.  :)

Yes, I think I should examine the prop if possible.  I'm assuming that Poser generates one hair polygon for every vertex of the parent prop which is part of the hair group.  Possibly you've found a prop which disproves this assumption.    Or, perhaps more likely, you've found the empty group error which I've been trying to fix.  I've only seen it once, and I haven't been able to repeat it in order to debug.  Hoping that's it.

I'll PM you will an e-mail address.

I've just updated the Loop Scripts page.  All of the scripts have been updated in one way or another.  The extruder now has animation enabled.  The path scripts all have the line preview options.  All of the Wx GUIs now have proper End Script buttons (a special technique is needed, to work with the poser.WxAuiManager & it took Cage this long to figure it out).

Quote - Belated birthday greetings to this thread.  :)

Ooh.  Cross-post.  My above response was to RedPhantom.

But this one is to SamTherapy.  The Loop Scripts project thanks you for the birthday greetings.  :laugh:  Has it been over a year of loop-making now?  Jeepers.  :laugh:    I had no idea what I was embarking upon, when I started.  :lol:

• Neither hair group nor hair prop exist
• Both hair group and hair prop already exist
• Hair group exists but hair prop has been deleted from scene
• Hair prop exists but hair group has been deleted using the Grouping Tool

It's also running a check, before creating a re-named group, to verify that no hair group which is identical to a selected geometry group already exists on the prop.  In that case it declines to handle the geometry group and refers the user to the name of the matching hair group.

One thing it can't do is delete a geometry group once it's been made redundant by being copied over to a hair group (which happens in the case of renaming to avoid duplicate actor names in the scene).  That will need to be done manually, using the Grouping Tool.

The error in restore_roots(), reported above, was possibly (hopefully) being caused by a hair group/hair prop mixup, in which a hair prop with empty geometry had been created.  If so, this update should fix the problem.  If the error persists, I still have some revision to do.  :unsure:

Sorry about all of the updates.  It's getting there.  I have a bunch of new options coded, which need to be built into the GUI, so hopefully the next update will be for features and not bug fixes.

Quote:...so hopefully the next update will be for features and not bug fixes.

Unless redphantom manages to break the thing again:m_wink:

Quote - Unless redphantom manages to break the thing again

Well, if there's anything that needs to be fixed, I hope you find it.  :lol:  But I'd rather hope that there's nothing to be fixed and you have no further troubles.

Well, so far so good. haven't gotten any errors with your laest script. Tried all the props that had caused errors and they all worked fine. 

I've also updated the chain posing script.  A BODY actor which doesn't have a zeroed origin can now be handled, and most of the base link posing errors seem to have been reduced to minor misalignments.

Quote - I just wanted to post a shot of something I made with the hair script. It's nothing fancy but it is all dynamic hair

Wow!  :laugh:  That's a much better result than I would have expected, based on my tests.  I ran into endless problems with script-manipulated guide hairs intersecting the underlying scalp prop.  I assumed that would lead to critical difficulties with a final hair set, then got caught up in trying to find ways to prevent the intersections, but did not (and still do not :lol:) have the math knowledge adequate to solving the problem.

It's really nice to know the script could help someone develop a working hair set, after all.  Was the process ultimately any easier than trying to make the hair without the assistance of the script? 

Yes it was much easier. I could not have done this without the script. I think each face of the scullcap would have had to be a new group otherwise.

I had problems at first with the hair intersecting the scalp too but then found that hair marker 0 and 1 need to pull the hair away from the scalp by angling them out some.

There is a bit of a learning curve, but I think it's worth it.

Well, we can safely say that you know more about using the hair script than I do!  :laugh:  Well done, RedPhantom!  :thumbupboth: 

I'll have to try tinkering with it eventually.  Real world stuff has kept me away from Poser for a couple of months now.  :sad:

Cool! :)

Laurie

Just found this thread, so haven't used it yet, but I for one think the hair script is a brilliant idea. Looking forward to having time to play with it.

Hm, where am I supposed to be seeing the path that I'm putting markers on? I don't see it whether I'm in the poser room or manage to get Python going in the Hair room.

I'm also getting an error: "TypeError: argument of type 'bool' is not iterable"

No doubt I've triggered that because I have no clue what I'm doing....

Oh dear.  You may have found a bug.  :scared:

What are you doing when you get the error?  I assume you're using the hair script.  You're using Poser 9 or Poser Pro 2012, correct?

Yes, PP2012.

It may be simpler to identify the proper workflow step-by-step than to figure out how I triggered it tho... not seeing the path I was expecting to see somewhere onscreen, I started clicking buttons like "Show Preview" and "Run Script" to see if that would make the path visible.

So... do I have to be in the Hair Room to start (that was my initial assumption, but then my Python menu "disappeared" [not really, but I didn't initially realize it had auto-docked when I switched rooms], so switched back to Pose)?

Here's what I'm trying now:

Select Face Camera

Go to Hair Room

Select hair parent, i.e. skullcap

Call the hairtopath6c.py (which I had put in Poser Pro 2012/Runtime/Python/poserScripts/Cage/ )

In the resulting GUI, start off with a hair group - in this case, "Hair_Front"

At this point, I get this error:

Traceback (most recent call last):
  File "C:Program FilesSmith MicroPoser Pro 2012RuntimePythonposerScriptsCagehair_to_path6c.py", line 3296, in fill_hairboxes
    result = self.stylist.get_hairprop(grp)

    raise PyDeadObjectError(self.attrStr % self._name)
wx._core.PyDeadObjectError: The C++ part of the wxGUI object has been deleted, attribute access no longer allowed.

I've always used the script in the Pose Room, myself, but I don't think it should matter whether you're in Pose or Hair.  Just as long as all of the tools you need to define groups and change the camera view are present.

I don't seem to be able to duplicate that error, which is troubling.  Can you tell me what you did when you got the 'bool' error?

Proper workflow?  (I'm going to try out bullet points now.  Please pardon.  :lol:)

• Create one or more groups on the skullcap or other prop from which the hair will be grown, using the Grouping Tool.
• Start the script.  Your groups should be listed in the "Select group" listbox.
• Upon selecting a group, guide hairs should be automatically created, if they did not already exist.
• Click "Add marker" to create the first hair marker.  This will be the base of the hair path.
• Add a second hair marker.
• Click "Show path" to display the preview path for the hair curve.
• Position markers to create the desired path shape, adding more if necessary.
• Adjust script settings as desired.
• Click "Run Script" to position the guide hairs for the selected group.

And, dang.  I notice that my capitalization is inconsistent on the GUI.  Hmm. 

The various settings... should probably be explained, too.  I'd have to play around with the script a bit to refresh my memory of the specifics.  :lol:

I can't seem to generate any errors, on this end, though.  The 'bool' error you reported looks like there's a bug in the script somewhere.  The latter error is a puzzle to me.    Has the script been able to give you any status updates in the status box?

The simple explaination on how to use the script.

load a scalp

create a hair group

grow hair

I do the rest in the pose room

make sure the scalp is selected

load the script

load a bunch on hair markers they show up at location zero on the floor so you don't want to be using the face cam at this point

move the hair markers up to be close to the head so you can focus on it.

use them to create your path (this is a good time to the line preview)

select a hair group from the left column

then either pick a strand from the middle column, a y-lock from the right column or don't select anything (This will apply to the whole group) and hit run.

note: if you try to run the preview with out any markers you'll get an error. If you leave the script open and change parameters in the hair room you'll get an error (but not if you close the script first). Changing many of the parrameters in the hair room will cancel out any work you've done with the script.

Hope this helps at least until cage can help you.

Good luck

Ooh.  Thank you.  :lol:  I am terrible at explaining things.  :lol:  :blushing:

yeah simple lol took me 20 minutes to type

I didn't know trying to run a preview without markers created an error.  D'Oh!  I've never tried that.  :lol:  Something to fix!  :laugh:

Thanks so much, guys. Maybe part of my problem is that I tried this on a hairstyle that I had pretty much otherwise completed. But the bigger thing is I had no idea where those markers were or how to identify them as a line.... or that I need to make my line before selecting the hair I was gonna style, for that matter. :p

I guess it's gonna have it's own learning curve, but should be doable.

Oops I was wrong about about the preview error. I'm sorry. Maybe that was from an old version. It's not causing problems now.

I apologize about the lack of documentation for all of these scripts.    My efforts at writing tutorials and instructions haven't turned out compelling results in the past.  :sad:  If you have any questions, I'll be happy to try to answer them.

Quote - Oops I was wrong about about the preview error. I'm sorry. Maybe that was from an old version. It's not causing problems now.

Well, that's good, at least.  :laugh:

I'm still concerned about the two error messages reported on the previous page, though.

Hey, hard to complain about lack of documentation when you're providing all this awesome stuff out of the goodness of your heart. :)

Not to mention if you had to document all these scripts, you wouldn't be make new ones at a break neck pace. :)

Well, I mean, a script isn't very useful, if no one knows how to use it.  "A weapon unused is a useless weapon," and all that.  :lol:

I'm setting up a Windows 7 64 bit system and beginning to understand the complications of UAC.  Has anyone had trouble with the line path preview for any of the scripts, on Windows 7?  I may need to change the way the temp file for that is being written.

I've also read in another thread that EnglishBob has encountered some errors in X-oriented chains created by the Chain Maker.  I'll see if I can fix that.

I think I'll be heading into a debugging phase for these scripts soon, so if anyone has found any bugs, please post them so I can try to fix them.  :laugh:

my pp2010/64 bit/win7 is installed to Documents, not Program Files, & i've never had a problem with any temp files or paths with your scripts.  remembering how to use them is another beast entirely, but i finally wised up & keep instruction texts in the folder with the scripts.

UAC is a PITA.

I've been assuming it's mostly a CYA measure on the part of Microsoft.  A lot of what was added with Vista seemed to be about making it easier for MS, or trying to make it harder to run bootleg versions of MS software.  Generally while making things worse for the average user.  But what do I know?  :lol:

We probably shouldn't get too off-topic with Windows complaints, though, lest the thread end up locked.  :scared:

Hmm.  Not sure what's causing it, offhand, but I will see what I can do about it once I finish setting up this new computer!  :woot:  Thank you for reporting the error.  I'd like to debug these as thoroughly as possible, but I haven't been seeing any errors on my end.
