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
         
         
            - Animate and constrain the same object.
            
 
            - Edit and key the pairBlend Weight attribute
               to animate the amount of influence the constraint and keyframe animation
               have on their target object. See 
                        Blend Weights in the Channel Box.
            
 
         
         To blend set driven key animation with
            constraints
         
         
            - Apply set driven keys and constraints
               to the same object.
            
 
            - Edit and key the Blend
                  ConstraintTypen channel on the constrained/driven
               object’s transform node to animate the amount of influence the constraint
               and driver have on their constrained/driven object.
