Quote - Any polygon that isn't black lights other polgyons. It doesn't matter why it lights them. It could be because it is lit by a light. It could be that it has a hard-coded ambient color. Either way, it is included in the general lighting.

My environment sphere is self-lit, using a photo to determine the color of every pixel. Therefore, it lights the scene, as long as something doesn't get in the way.

A rectangle with an "Exit" sign in ambient red also lights the scene. Nothing special about it.

No disrespect to you BB but that sounds pretty damn special to me. :D
