Dear All,

First, thanks in advance for your advices.

I have to create videos, that will be projected in a room for a concert, on 5 surface: walls (left, middle, right), floor and ceiling. The projections should be linked together, and elements should be able to go from one surface to the other.

I'm facing a problem when creating my videos in after effect. I started from a big composition where I will add my visuals:
From this composition, I built a 3D space (just to simulate the space), composed of compositions. I can't figure out how to have a clean junction between the screen, for exemple to move an item from the left green square to the top green rectangle, because it would go into the grey area and therefore not be displayed. Here is an example with a grid: I guess I'm taking the wrong direction to build up my files, so if you have any other technique or solution to solve that, I would be super grateful.

Thanks a lot.
