I've got a problem when trying to use 3D on a 2D project. I've setup 3 planes and I'm trying to rotate the center. When I do this, the planes that are supposed to go "behind" stay on top of the other ones!
I don't know how to explain than the small video here:
PS: it's the first time I'm doing this, if it's against SO rules I'm sorry.
I've solved the problem by creating 4 canvas: one canvas for each side, and I move the camera around.
