You can apply motion
            blur to an object rather than to the entire scene. To use the per
            object motion blur, you must apply Motion Blur globally, and then
            disable motion blur per object.
         
         NoteThe motion blur curve
               in the Action Setup menu is global. It cannot be set per node.
               When motion blur is enabled, all surfaces have the same blur characteristics
               but not necessarily the same animation.
            
         To blur a single object:
         
         
            - Enable Motion Blur in the Action Setup
               menu.
               This activates a global
                  motion blur applied to everything within the scene.
                
- Disable motion blur per object (for example,
               in the surface, axis or light menu) to exclude objects from the
               global motion blur.
