Another method to simulate shadows is to modify a duplicate of the object being lit.
Light sources are not visible. You can simulate a visible light source by combining a
point light and an image or shape.
Note: Use the Match Move behavior to move a simulated light source with a light in a
movie clip. For more information on the Match Move behavior, see “Match Move
Workflows” on page 58.
