The Character Face Definition pane lets you create a set of facial expressions for your character by blending together shapes or clusters.

Character Face Definition pane A. Active option B. Expressions area C. Target Models area D. Preview pane

You can create your own custom expressions using the Custom pane, or use the Generic pane to define preset generic expressions for connecting to an Actor Face.

Regardless of which expressions you are defining, you must first Alt-drag models with shapes or clusters into the Target Models area. You cannot define expressions until a head model with shapes or clusters displays in the Target Models area.
