The Actor Face asset lets you animate a character’s face by transferring animation data from a motion source to a Character Face.
You can use an Actor Face to define a facial Marker set for a motion capture device or for facial motion capture data, then connect the Actor Face as the motion source of a Character Face.
An Actor Face is mapped to motion data using a set of markers called a facial Marker set. This facial Marker set maps markers or sensors of motion data to the specific locations on the Actor Face that they control. You can manipulate and plot the marker or sensor data to the Generic channels of the Actor Face, then clean-up the data by keyframing directly on the Generic channels before plotting the animation to your character head model.
