Some effects can use a composition’s camera and lights. These effects include Card Dance, Card Wipe, and Shatter. Some of these effects always use the composition camera, whereas others include light and camera options in the Effect Controls panel.

When you apply an effect with a Comp Camera attribute to a 2D layer, the effect can track the composition’s camera and light positions and render a 3D image on the 2D layer that it is applied to. The effect’s results appear 3D; however, the layer with the Comp Camera attribute applied remains a 2D layer and consequently has the following characteristics:

• 3D layers above and below it in the Timeline panel cannot intersect with each other or cast shadows on each other.

• It cannot intersect with 3D layers or cast or accept shadows.
