Using Masks

For spotlight effects and transitions, you can use a mask layer to create a hole through which the contents of one or more underlying layers are visible. You can group multiple layers together under a single mask layer to create sophisticated effects.

To create a mask layer, you place a filled shape on the layer. Right click on the layer to bring up the layer menu. Select MASK.

The mask layer reveals the area of linked, underlying layers that lie beneath the filled shape, and it conceals all other areas. Mask layers can contain only a single shape, instance, or type object.

You can use any type of animation, except motion paths, to make the mask move. You cannot mask layers inside of buttons.
