ust to clarify the lighting, there are 2 lights in this scene. a spot light just outside the windows, and a point light in the floor lamp. The rest of the light is emitted from the cieling, both bounces are set at 2.

 

Did you notice any artifacting issues? I was wondering if raising emitters and lowering IDL intensity is really increasing Ray success. I mean, it's missing the target less and not leaving blanks/splotchies.

Cannot wait to post my next render... sheeez

 

The spheres I was using was for exterior shots but I tried to bounce it into the room with 6 or 7 bounces. It's just easier to do it with a spot We still need a way to emit light and still be able to be selected invisible to some other selective surface. This was what carodan was after, I think. Reflections in the eyes are a perfect example when using hot emitters.
