I’m going for something like this:

In that navigating the menu is done by rotating the cube. I had problem scaling the object though, to fit the entire screen, so I tried using a different Canvas Render mode.

The problem is when two panels are parallel to each other. One renders on top of another, so the contents of the front aren’t visible. Should I apply a material to the panels?
