Relighting: Casting Shadows
You can create realistic 2D and 3D shadows in your Action scene by using lights to cast and receive shadows,
as well as self-shadow (an object can cast a shadow on itself).
After adding and setting up shadow casts in Action, you can output the shadow by itself, or as part of your
overall composition. A shadow pass is a white image with greyscale regions that represent the shadow
coverage. See
Output Options (page 483) for information on the specific shadow output settings.
Action also supports drop shadows (see
Adding Drop Shadows (page 520)).
