No, it’s not too complicated! Let me try to explain it a little better:
So, let’s say a room has four walls. Each side has a different object- one with a bed, another with a window, one with a desk, and the last with a door. Now let’s say you have a background of the bed, but you need another point of view. So you get a background with the window… does that make sense?
Sorry if that’s still confusing
