Retarget animation from one skeleton to another

Note

When your skeletons have an IK, FK, and an IK/FK skeleton, then choose just one of the types of skeletons on which to perform the retarget. For example, source FK skeleton > target FK skeleton.
The results of your retarget will be the most reliable when the source and target skeletons have the same types of labels (for example, both skeletons have Neck labels, or neither skeleton has a Neck label). See Joints in the target skeleton are rotating on the wrong axes.

To retarget animation from one skeleton to another

Set the neutral poses for your source and target skeletons.

Make sure that all your source and target skeleton’s joints are labelled properly.
See Label a skeleton’s joints.

The first root you select is considered the source, and the second root you select is considered the target.
