Using Parallel Operator and Body Masks on Motion Behaviors it is possible to mix motions on different parts of the body.

This is very useful to create new motions from already existing ones, or completing motion capture motions for which some parts of the body (fingers...) we not captured.

Given 2 input motions

Sit Motion

Wave Motion

We can set body masks on each Motion Behavior to replay

• Pelvis + Legs + Head on the Sit Motion
• Spine + Arms on the Wave Motion

Here is the result of this setup on each motions

Sit Motion with body mask	Wave Motion with body mask

When both Motion Behavior are in the same Parallel Operator, they replay their own animation on the unmasked body parts

Which gives the following result:
