I noticed a trick in a 3D scene I was reviewing. It was a rectangular room, and whenever the camera faced a certain wall (the one that tend to be in the way of a shot of the room) it would disappear, and only reappear when the camera rotated around the room. This allows you to take more wide angle shots of your scene without exterior walls that aren't meant to be in the shot getting in the way. I looked up on Autodesk's website to find out how to do this. It only works on planes, so I had to delete my cube polygon wall structure and replace it with 4 planes:
I added thicker cube polygons walls though for the stairway as I won't be taking a shot from behind the stairs:
The trick is to toggle with the planes render stats, preventing it from being double sided so it only shows up when the camera is facing one of its 2 sides. Rotate the planes accordingly only certain walls will disappear when the camera faces them, making it easier to take wider shots of the scene:
