Working in Cycles.
Say I have a "disco ball" with a glossy shader. I'm pointing a spot light to it, and I'm trying to have the reflections of that light illuminate the diffuse material on the walls with the patterns from the ball.
I get this:
but I'd like to get something like:
For the illustration I placed a point light inside the ball an removed faces. But what I'd like to do is move the light around the ball so that the light reflected from it changes like it would do in real life.
Is that possible at this point?
Just for the record here's the image rendered in LuxRender (yet another program to learn...)
