Hi all,

I am a relative novice to rendering and upon recently discovering the added realism achievable using the 'final gather' mode I'm trying to set up a new generic virtual studio for rendering simple scenes. The lighting I have so far is just the sun and a spotlight and although I'm quite pleased with the results I'm struggling to get the apparent brightness of the materials correct. At first the desk top material appeared quite washed out so I've cheated and compensated with the image file. However the grey materials still appear to light, and the floor a bit too dark (I'd like to be able to completely white the floor out appart from the shadows). I've made the adjustments I can using the self illumination control, but they are at the ends of their ranges. Also I don't want to weaken the shadows too much as I quite like the way they're turning out.

Anyone have any tips for me about how to control brightness of materials beyond just persevering with tinkering and such.

Thanks in advance Autodesk forum.

Lovely image. I keep looking for the OMO button to get them whites white.
(Is OMO australian?).

Thanks a lot! It's come on a bit since that point although I think I'll go back to that one try and get it working better as I need a generic scene for doing quick renders. This is a version of the same scene, I had more luck combining sun and interior lights within a room. The subject isn't as exciting as we're using a white laminate rather than a wood finish (so hard to get looking good).

The 'RENDEREXPOSURE' function is invaluable it seems in balancing light effects, although I'm still struggling to get my blacks as rich as I'd like. It's almost as though I need a minus value on the self illumination of materials. Maybe next I will try turning the lights right down and then bring the brightness of the intended parts back up.

What is this OMO you mention? what does OMO stand for.

It is apparently a brand of detergent sold in Australia and elsewhere.

I do not recall hearing of it or seeing it here in the eastern US, but I have heard of Unilever. I suppose Wisk would be the equivalent product here. They have quite a list of "well known" products (Ben & Jerry's, Breyers, Dove, Klondike, Popsicle, Q-Tips, Ragu, Skippy and Vaseline, among others).
