The Expressions area lets you define custom or generic expressions for your Character Face.
Once you define expressions, you animate them in the Character Face Animation pane using either an Actor Face asset, keyframe animation, or a Relations constraint connected to the Voice device.
Use the Custom pane in the Expressions area to define your own custom expressions. Custom expressions can be whatever facial expressions your project requires, including expressions that represent phonemes and are linked to the Voice device.

For example, you can create an expression, such as a surprised face, from a blend of shapes for the eyes, mouth, eyebrows, and other shapes.
The Generic pane in the Expressions area displays a basic set of facial expressions used to connect the Character Face with an Actor Face.

An Actor Face lets you connect the Character Face to motion capture data from either a live source or imported file.
