Would be nice to be able to add a mask in the output transformation menu, not the input selection. After transformation the mask can get out of shape. But more importantly to me I want to be able to project the same layer with two projectors, yet be able to mask each individually.
Is this possible?
Here's what I mean (rough illustration, mask is in red, not black):

Here's what I tried to do and felt the need for this:
I was projecting a video on the wall, and also on a white box in front of it with another projector.
The first one needed a mask so it wouldn't project on the box itself.
If I'd create a mask in the Input Selection menu, that would affect both projectors.
