Thanks for the quik response. I’ve found this info, in case anyone out there could use it, which is definitely different than what I’m asking, but may help with part of the problem;
> The only thing you can do with reference to the environment light is to add a box around your room. Then give that box a material that has ‘only in secondary’ checked. This will bounce the light back into the room but won’t be visible to camera.
Pretty interesting idea, and I will be trying this.
UPDATE: The quoted text above is better contextually filed under “Near Clipping Plane” - just an fyi. I don’t think there’s a Camera near/far clipping plane option in either rhino or vray here
