You can save an animation containing honored constraints across layers in a
BIP on page 7923 file. However, if the layered animation links to another biped
as reference, that link is not saved with the animation.
Procedures
Example: To Maintain IK Constraints Across Layers:
This procedure takes into account the fundamentals of animating across layers
and expands on the concept of honoring IK constraints.
1 Prepare a biped with IK keys on its feet, and its left hand constrained to
an IK object.
2 Select your biped and expand the Layers rollout on the Motion panel.
3 Create a new layer and rename it Low center of mass.
The Retarget Left Arm button in the Retargeting group becomes active,
which indicates that the current layer honors the IK constraint of the
base layer for this body part.
