What are Expression Set and Viseme Set

In Character Creator, each character can talk and make facial expressions with lip-shapes with the help of Expression Set and Viseme Set. They are actually two sets composed of numerous sliders which can be used to trigger facial expression and lip-sync.

Expression Set

The Expression Set contains official expression sliders which are closely related to the Face Control Systems, such as Face Key Editor, Face Puppet, Motion Live, Auto Blink, Look At.. and so on.
