About combining animation and tracking data

When the destination object in a match move operation has no animation of its own, it precisely follows the motion of the source object. However, if the destination object is animated (has its own applied behaviors or keyframes), more complicated motion effects can be achieved by combining motion paths.

You can specify whether the animation of the destination object is ignored by or added to the Match Move behavior. You do this in the Match Move Behaviors Inspector, by choosing one of two options from the Transform pop-up menu: Attach to Source or Mimic Source.

• Attach to Source: Applies the movement of the source object to the destination object, but disables any animation inherent in the destination object. (However, you can reactivate the destination object’s own animation and deactivate the source object’s recorded track by turning off the Position, Scale, and Rotation buttons in the Adjust row of the Behaviors Inspector.)

• Mimic Source: Combines the motion paths of the source object and destination object’s own animation. In other words, the destination object maintains its own animation while at the same time mimicking the motion in the source object’s recorded track. When the Match Move behavior is set to Mimic Source, turning off the Position, Scale, and Rotation buttons deactivates the source object’s recorded track.
