Animation-Constraint blending

 
 
 

You can blend keyframe animation and constraints on the same object. See Animate and constrain an object and Animation-Constraint blending workflow.

When both keyframe animation and constraints are applied to the same object, a pairBlend node is automatically generated. See pairBlend. All the object’s animation and constraint channels are linked to the object through this pairBlend node.

You can modify the weight of the animation-constraint blend to generate various effects. This Weight attribute is on the pairBlend node. See Blend Weights in the Channel Box.

Note
  • 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.
