Quote - bopper, the terminology is confusing because there are two uses. When we speak of "Light emitters" we usually mean something that is generating light from within, i.e. a prop with Ambient turned on. The "Light Emitter" setting on the Properties tab means something else, viz, that the item is included in IDL calculations so that it reflects light.

This is the maddening thing, though.  If body parts are really close together, the light bounces around unrealistically and it looks like they're glowing.  It's vexing when you've got characters holding hands, or fingers really close to a body part.
