I see. So it’s a materials issue, not a geometry issue. I’ll give it a try, thank you!

Not quite. Let me take what you said a bit further and see if it makes any sense then.

Create a cube, make editable, select a face, but delete key. Then put an object into the box. If you look inside the cube where the hole is, you can see the object and the interior of the box.

What I’m going for is that when you rotate around the cube, the exterior polygons are not shown so that you will always be able to see the remaining internal faces. As well as the object inside the box.

Hopefully this description makes sense.
