Locking a mask


    Locking a mask prevents you from selecting it in the Timeline, Composition, and Layer windows or setting it as a target in the Layer window. Use this feature to avoid unwanted changes to the mask.

To lock or unlock a mask:

  1. In the Timeline window, expand the Mask property.
  2. In the Switches column, click the box underneath the lock icon (the Lock icon) next to the mask you want to lock or unlock. A layer is locked when the lock icon appears in the box.
