Re: [Maya-Python] Re: transfer vertex ids between different

[Rudi Hammad]

Here are the reason why I prefer the cut out(maya 2022 and previous) :
1. it is cleaner in the sense that you don't need to have an entire body if 
your are just movind points in the head. 
2. the file size where your keep your blendshapes will be smaller. You 
might not notice this is cartoony characters, but if you are working with 
high res geo (like in realistic character) you will feel the impact in size 
and loading times.
3. if the body topology changes, all your facial blendshapes are still 
safe. Even adding an extra loop in the fingers later on will mess up all 
your facial blendshapes.
4. cutting out the head will allow you to display the head with different 
LODs. You might get 24 fps with one char in the scene but if you have 4, i 
hardly see it will keep up to 24 fps. If you cut out the head you can 
display it with a procy
  body so you will have 24 fps with many chars in the scene.

In a nutt shell I find separating the head a cleaner and more optimize 
design. Just do what ever you think is best for your workflow.

 Actually I is possible, I did figure out how to do it. If you 
 separate the head from the body, duplicate the head, and then 
 recombine the 
 head to the body, vertex order is preserved.
 Then you can do a blendshape. I'll probably end up writing a 
 deformer anyway, but that's a nice little trick there.

Re: [Maya-Python] Re: transfer vertex ids between different

[stephenkmann]

Yes that's what I'm saying Roy,
  You no longer need to separate.. as the morph deformer will act like a
blendShape to the joined full body/head .

If you don't need it to be connected.. like the neck goes under a shirt.
then sure..   I prefer separate shells,,, ( I am not a multi shell poly
fan)

but for characters where you have the head and neck connection visible as
it flows into the body,, then  I don't bother to cut the head off and go
thru the rig-a-marole of cutting off and re-ordering and re-connecting
hack.
Dropping your verts out of the blendShape deformer will result in a similar
performance and file size.  or if in 2022 you can use the morph deformer.

 Also, I usually found the performance hit of having a connected head to

 remove the body components from the blend shape.

 I'd be curious if the head cutting off is still necessary , and in what
 cases..

 what i suggest to do instead is match vert by world position, or if

 get the closest vert, for every vert. and hook them up in a tuple.
 then use this to do anything you want. ex transfer skinning.

 i suggest to do this with openmaya because of speed
 it will be very slow in pymel

Cool stuff about the morph deformer. I just need something that works 
across previous maya version. Thanks for the ref.
About separating the head it simply how I like to my rigs. I used both 
method in different production and still prefer the cut out.

 yes, i want to have different topologies. The use case would be a 
 rig where you have a mesh cut out of the head for the facial rig, that 
 you 
 blendshape into the full body mesh. So there you have 2 different 
 topologies. In maya you can do a blendshape between different 
 topologies 
 but if the ids don't match you get unwanted results.
 I can achieve that alternativly wrighting a wrap deformer , but I 
 was wondering  by beeing able to match the vertices ids it would be 
 easier.

The button should only be able to attach to a single layout, because the
layout takes ownership of its position. You should try creating a second
instance of the button for the second layout.

[Maya-Python] Multiple optionMenu lists working with one directory problem

[Anastasia Korol]

Hi guys! I am doing simple UI for choosing textures for two nodes in the 
shader and I can't make the optionMenu command to work one by one with the 
same source for the both optionMenu1 and optionMenu2. I have one directory 
to choose and need two similar lists where user can choose the texture file 
and apply it on two different nodes. So far I am interested only in 
understanding how to make both of the optionMenus work with one folder 
button:




import maya.cmds as cmds
from os import listdir

class AK_TextureLink(object):
def __init__(self):
self.window = 'ShaderWindow'
self.title = 'Layered Shader Window'
self.size = (600, 250)
self.createWindow()

def createWindow(self):
if cmds.window(self.window, exists = True):
cmds.deleteUI(self.window, window = True)

self.window = cmds.window(self.window, title = self.title, 
widthHeight = self.size)


self.mainForm = cmds.formLayout(numberOfDivisions = 100);

self.titleDisplay = cmds.text(label = self.title, align="center", 
font = 'boldLabelFont')
cmds.formLayout(self.mainForm, edit = True, attachForm=( 
[self.titleDisplay, 'top', 5],

 [self.titleDisplay, 'left', 5],

 [self.titleDisplay, 'right', 5] ))
 
 

self.titleSeparator = cmds.separator();
cmds.formLayout(self.mainForm, edit=True, attachControl = 
[self.titleSeparator, 'top', 10, self.titleDisplay],
  attachForm = 
([self.titleSeparator, 'left', 5],

[self.titleSeparator, 'right', 5] ))

 Not an answer to the question, but the separated mesh rig-blendshape 
workflow can be much optimized in Maya 2022 using the new Morph deformer: 
https://youtu.be/Cdow0UVZfBI?t=1605
In particular the "partial deformation" around 28:10 he states it and 
starts showing after. :) No need for actual merging of meshes, etc. - 
That's prone to get slow!

 Then you can do a blendshape. I'll probably end up writing a deformer 
 anyway, but that's a nice little trick there.

Re: [Maya-Python] Re: transfer vertex ids between different

[stephenkmann]

Why are you separating the head.. you don't really need to do that
technique any more , now that there is the morph deformer...

Also, I usually found the performance hit of having a connected head to
body with morph targets was never really that bad.. especially if you
remove the body components from the blend shape.

I'd be curious if the head cutting off is still necessary , and in what
cases..

 get the closest vert, for every vert. and hook them up in a tuple.

that's true when it stays separate, but when merging the 2 pieces together

 yes, i want to have different topologies. The use case would be a rig
 where you have a mesh cut out of the head for the facial rig, that you
 blendshape into the full body mesh. So there you have 2 different
 topologies. In maya you can do a blendshape between different topologies
 but if the ids don't match you get unwanted results.
 I can achieve that alternativly wrighting a wrap deformer , but I was
 wondering  by beeing able to match the vertices ids it would be easier.

Actually I is possible, I did figure out how to do it. If you separate the 
head from the body, duplicate the head, and then recombine the head to the 
body, vertex order is preserved.
Then you can do a blendshape. I'll probably end up writing a deformer 
anyway, but that's a nice little trick there.

Re: [Maya-Python] Re: transfer vertex ids between different

[Hannes Delbeke]

match by vert id is impossible in that case because the vert ids cant ever
match, unless you somehow reorder the verts yourself from the mesh with the
most verts(the body)
what i suggest to do instead is match vert by world position, or if you
have unique UVs by UV position.

get the closest vert, for every vert. and hook them up in a tuple.
then use this to do anything you want. ex transfer skinning.

i suggest to do this with openmaya because of speed
it will be very slow in pymel

Re: [Maya-Python] Re: transfer vertex ids between different

[Rudi Hammad]

yes, i want to have different topologies. The use case would be a rig where 
you have a mesh cut out of the head for the facial rig, that you blendshape 
into the full body mesh. So there you have 2 different topologies. In maya 
you can do a blendshape between different topologies but if the ids don't 
match you get unwanted results.
I can achieve that alternativly wrighting a wrap deformer , but I was 
wondering  by beeing able to match the vertices ids it would be easier.

Re: [Maya-Python] Re: transfer vertex ids between different

[Alok Gandhi]

Ok. Btw, I am curious as to how you would transfer the vertex id for two
differing topologies. Can you give some details about what's different
between the two topologies. In any case, I assume that they have the same
number of vertex (otherwise you cannot transfer the vertex ids).

Re: [Maya-Python] Re: transfer vertex ids between different

It looks similar to maya's transfer attribute tool, but it doesn't look to 
do a vertex id transfer.

Re: [Maya-Python] Re: transfer vertex ids between different

There was GATOR

is Softimage XSI that could handle such cases as yours. I remember vaguely
that it was being worked upon in Maya (since the Softimage dev team was
merged with the Maya team). I am not sure if it exists in Maya in some
form. Maybe someone here has more information and can comment.

That was to nice to be true. So I guess there is no easy way (or no way at
