Quote - I think if you want the glow to extend beyond the physical light you need to create geometry for it and a shader. I saw BagginsBill tutorial somewhere on this and can't remember where.

Look at the quick pic I posted. The tube is acting as a light emitter as you can see on the ball. There is a thread on this subject for P7 in which a Gather Node is attached to the object that you want to illuminate with your light. It may be that to which you refer. Since the question refered to P8 this is the easiest way to make a prop a light emitter that I know of. I'm gonna search for the thread you mentioned though to see if there is an easier or better method.
