Hey, thank you so much for the very detailed answer.
You know how in some biased renderers, you can add a point light somewhere, and it will help illuminate otherwise dark areas?
I'm trying to do the same thing, basically.
One thing I don't understand is surface illumination, regardless of whether I switch it on or off, the light effect looks identical to me. What's the difference?
I do want to retain the reflections of the light.
My scene is simple: a cylinder with a very glossy surface and a bump map, and a plane nearby with an emittance, sort of like a studio spot light. The result is that the inside of the cylinder is very dark. I want to light that up a bit to bring out the bump map.
My solution was to place a small plane right above the cylinder opening, but of course I just want the light effects (illumination and reflection) and don't want to see the geometry.
The render passes idea sounds intriguing. And what did you mean when you said something about hiding the geometry, without setting it to opacity zero?
Thanks again.
