Working with multiple masks in one layer

When you create masks in a layer, the mask names appear in the order you create them in the Timeline window outline. To organize and keep track of your masks, rename them as you would rename layers. (See Renaming a layer.) When creating additional masks for one layer in the Layer window, make sure that the Target pop-up menu in the Layer window is set to None; otherwise, you will replace the targeted mask instead of creating a new mask. (See Specifying one mask as the target for animation.)

To make it easier to work with multiple masks in the Composition window, you can apply different colors to each mask outline.

To apply a new color to a mask outline:

1. Select the mask in the Timeline window.
2. If necessary, expand the Mask properties by pressing the M key.
3. Click the color swatch just to the left of the mask name, pick a new color, and click OK.
