Heads with geometries for eyes and mouth

[Karla]

bailenson suggested a texture solution.
I made the below arbitrary example (edited .jpg file attached) after following this thread:
<http://www.worldviz.com/forum/showthread.php?t=776&highlight=texture+avatar>

I see now how different textures can be put on the avatars to look like the eyes are moving (if the .jpg on the head has eyes that are looking left/right/etc. from edits using image software like Paint/Photoshop/etc.).

If anyone has answers to may first post above, I welcome them.

Thanks,
Karla

If you want the eyes to be separate objects then you have 3 options:

1) Use 3dmenow 2.0

2) Manually add the eye geometry to your model using tools like 3dsmax. This option will require you to be somewhat experienced with 3dsmax.

3) Use the face that comes with Vizard which has separate eye geometry. You would be able to apply different textures to it, but the geometry won't change though.
