In my scene, I have an image plane with a picture of some kitchen tiles. I also have a cube which has been UV unwrapped and has the same texture as the image plane, but positioned so that the front face of the cube fits to one of the tiles.
I want to have the front face which has also been separated by selection so that I can open it like a lid and 'see' inside the cube.
The problem is that the image plane cuts into the cube. How do I mask the area where I want to see through to the cube behind?
Please also look at my BLEND FILE if you can help.
