Masking

[sbtamu]

This is kind of embarrassing of me to ask since I am a long time user of AS and long time member of the forum. When masking, is there a way to reverse the way the masking works as is? I mean, the shape you create will hide the above layers leaving the stuff out side the shape visible? In other words I want to mask and make the shape a hole leaving the outside visible.

Make the group show all and the mask subtract.
