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.
