You can modify masks in many ways. By modifying a mask's position, shape, and color, you can change the visibility of masked objects. You can also change a mask's type and the way it is applied. In addition, masks can be replaced, disabled, or deleted.

The results of editing a mask are immediately visible, even if the mask object itself is not visible on the canvas. The mask thumbnail in the Layers panel displays the edits you make to the mask.

Masked objects can also be modified. You can rearrange masked objects without moving the mask. You can also add additional masked objects to an existing mask group.
