Creating and importing masks

Creating masks

You can create one or more masks for each layer in a composition using any of the following methods:
•
Draw a path using the tools from the Tools panel.
•
Specify the dimensions of the mask shape numerically in the Mask Shape dialog box.
•
Convert a motion path to a mask.
•
Convert a channel to a mask using the Auto-trace command.
•
Paste a path copied from another layer or from Adobe Illustrator or Adobe Photoshop.
•
Convert a text layer to one or more editable masks using the Create Outlines command.
When you create masks in a layer, the mask names appear in the Timeline panel outline in the order in which you
create the masks. To organize and keep track of your masks, rename them as you would rename layers. When
creating additional masks for one layer in the Layer panel, make sure that the Target pop-up menu in the Layer panel
is set to None; otherwise, you will replace the targeted mask instead of creating a new mask.
