Question

I’m looking to create a puzzle game where the main mechanic is you moving and turning a 2d slice of a 3d level in order to make it possible, in one situation to the right is a wall, then, you turn the slice and, there it is, an opening. But how could I get the basic form of this working? Would I use the 3d section, or the 2d one? or even both? 3d or 2d nodes? Thanks in advance

edit: since I don’t know what to do about object clipping with the camera your on your own there, at least until someone else more knowledgeable about this shows up
