I'm working on a project to visualize a multi-story building. Each floor in the building is rendered as a rectangle, with a GIF of the floor plan as the rectangle's material.
The problem I'm having is when I stack rectangles/floors on top of each other, the lower floor always overlaps the upper floor:
But when you rotate your camera view to view the floors side-on, you can see that indeed there are two distinct shapes, one on top of the other:
In the two images above, the first floor is at ground level, while the second floor is at 50 meters (to exaggerate this effect).
Any help in resolving this would be greatly appreciated.
