In order to drive a character using motion data, you must first connect the data to an Actor, then select the Actor as the motion source for the character. The Marker set is the link between the magnetic or optical data recorded from a live performer and the Actor asset.

Creating a Marker set matches the motion data to the Actor’s body parts, letting you preview how the motion data will make a character move. In the Viewer window, a defined Marker set displays as a group of white markers attached to an Actor.

Actors and the Actor settings are used to define the Marker set for a motion capture device or data.
