I just went and played around some - a radial light won't stream the way you want - it just doesn't do it. You need to use a spot light to get a streaming effect. The way I was suggesting to fake it would be done like this - imagine there's a cube inside your sphere. The face of each cube is really the "mouth" of a volumetric spotlight...I've never done it, but I think the edges of the spotlights would have to overlap so that there wouldn't be an edge ... All that said, I just tried to implement my suggestion and the render choked my PII250/512meg machine...so, take what I'm saying with the appropriate grain of salt. Bottom line, is I guess, you may have to fake it with spotlights in some configuration to simulate the radial light inside the sphere. TomD
