Thank you Greg. I´ve always read about this method you mention, being the most
effective. (render out lypsinch/moods to alpha) and use themas texture sequence
on facial model. (effective = render times).
I got a really basic version working now, here´s the link on my own setup:2D

Hi Dave,
I've done this in the past using just the FX tree. You can drive the translate
2D node in the FX tree with locators in 3D. Translating the eye locators
(normalised to a parent) exporting that to a compositing sequence. All alphas
etc where cut in the FX Tree. I had several locators in the 3D scene to change
the shape of the eye. Then projected it back onto the 3D face pre-render.
Sorry, can't help with the details was a number of years ago but definitely
possible.
Regards,

Hi everyone, I´ve been trying to setup a 2d facial rig onto a 3d face (just a
simple sphere) to accomplish something like this:

So I´ve attached the setup I got so far (see attachment) and what I´m basically
doing is:1. create a sphere and uv unwrap it.2. Create 3 separate files (one
for the left eye, one for the right eye and one for mouth) with transparency on
.png format
3. Create a shader in the shader tree connecting all 3 of them using a constant
node for each into a Color1, Color2, Color3 layerson an Mix 8 Color node for
the shader on "alpha" as it´s blending mode.All working fine until now.
But here´s what I can´t get straight:
How can I manipulate the eye´s position like in the video?- I already tried to
setup 2 subTexture projections from the UV editor, but they slide all other
textures (eyes and mouth). Even if I make enough subdivisions on the face (the
sphere) to separate them from each other, the texture would still slide as I
move either subTexture projection.I´ve tried tearing the polygon segment for
the sub texture projection but as I resize the subtexture projection on 3d view
and then match it insidethe UV editor, it also distorts the texture.
I can see on the video the eyes are an image sequence, rigged with the visual
panel on the top right.I was told that doing a case by case setup for the 2d
texture (either left or right eye) via FXtree it´s way too heavy if I got 20+
textures for each eye.(There´s a video or RayFigs explaining how to set this up
on the FX tree).And so, I was recommended that I do the texture swapping via
ICE with ID_Attribute. But I´m getting confused; because I don´t exactly know
how to mix 3 different files (eyes and mouth.png) on the ICE tree and display
them all together working on the viewport.
The softimage viewport isn´t helping on all of this, since it will only display
the last texture plugged into the shader tree. The FX tree setup *DOES* display
the image and the viewport correctly. But I don´t know how to put the pieces
together to make the shader tree work on ICE scenario.
Could you guys lend me a hand on this kind of setup, please?Thanks! :)
