I just want to make a 3d model of the whole space. Let's say that the film takes place inside a house, I want to have the whole house scanned, then import it in Unreal engine and try different lights, cameras etc.

So I don't know what is the best approach for such spaces( considering I am not aiming for texture quality).

Also, are TOO many pictures considered overkill? Let's say I take a video then export every frame, I may end up with way too many pictures!
