Animate and constrain an object

Tip:

• Since animation-constraint blending lets you transform the constrained channels of a driven object, you must lock the constrained channels that you want strictly influenced by the target objects.
• After transforming a constrained object, you can retain its new translation, rotation, and/or scaling by reapplying Maintain Offset from the Modify Constrained Axis Options window. This prevents the constrained object from snapping back to its original translation, rotation, and/or scaling when its target objects are transformed.

To blend animation and constraints on the same object

1. Animate and constrain the same object.
2. Edit and key the pairBlendWeight attribute to animate the amount of influence the constraint and keyframe animation have on their target object. See Blend Weights in the Channel Box.
