mask inside another mask

[Amination]

hello Everybody!

I've just Strated A New After Effects Project And Faced with a problem. I have An Object in my footage which should be Parted from it's background. So i used Mask To Seprate the Object.

Now, The Object have Some Hole in it which you can still see the background through them, so they Should be cut out too. the Problem is that a mask doesn't Work Properly Inside Another Mask Area.

It just do nothing, But I Want it to cut those left over Parts too Like it it did for the object itself..

I'm using Aftereffects 2022 and gonna leave some Screenshots to help you understand the situation.

You can use different modes for your masks so that they add or substract from the selection.

what do you mean about "Mode"?

[Szalam · Accepted solution]

Mask modes give you control

I'm referring to mask modes which let you pick how the mask works.
