Enhance facial animation capabilities and tools to enable... -Facial Action Coding System (FACS) based rig. -Adaptive rig: which allows combining any number of expressions using optimized list of blendshapes. -Real facial muscles constraints: the advanced rig logic simulates real facial muscles constraints. -Advanced skin shader: adding wrinkles maps and pores stretching. -Easy to manipulate using facial controllers and/or GUI. -Smooth transition between all the expressions. -Adjustment layer: freeform manipulation of multiple regions of the face to create unlimited variations of the same expression.
