When we update JKA to a new animation system, I will revise my Ahsoka model to support the new eye and face animations. I'd love to see her face show more colour.
This is exactly the purpose of my Jan Ors Hi-Def head project (@eezstreet). It will incorporate new, complete lip-sync visemes animations and 6 variable facial expressions (fear, joy, sad, disgust, surprise, anger).
@Cerez -- bad smile "v" shape... one reason is that the game doesn't support strecthy bones which the mouth/lips would need... but there is a way to set up fixed-length bone chains to achieve same look using some clever control techniques-- which my new facial rig will use.
