When you have brought a character model into MotionBuilder and set it up for animation, there are three different types of motion sources you can use to animate the character: A Control rig, an Actor connected to motion data, or another character.
The overall workflow for animating characters in MotionBuilder can be summarized as follows:
See Character mapping and Characterizing.
See Creating a Control rig and Plotting animation to a Control rig.
You can also use the Control rig alone to create poses and set keyframes to animate it.
See Refining Animation.
The Flexible Mocap workflow enables you to use a flexible and open solving solution based on HIK or your custom solver and to efficiently apply with ease and precision optical motion capture data to your HIK defined character skeleton. The ability to select markers as a source, modify the input markers, adjust or override the extraction solve, and stretch the characters spine and neck all contribute to the precision and realism of the resulting solve.
