I'm setting up a scene in a small room, lit with two overhead lamps. They're old style incandescent, and I've used two point lights with a slight yellow cast, which seems to do the job well.

Thing is, should I also use IDL? The room itself is enclosed, with no exterior light source but I wondered if IDL would be worth adding for a bit extra something or other. Obviously, I need to keep the point lights for shadows and so on.

yes i would use IDL in this case.

Thank you. I'll give it a shot.
