Raytrace

[ABC Denver]

I am trying to raytrace one of our 3D vies but no matter what options I change, it always comes out way too bright. I have adjusted the radiosity and other options and can not find any combination that doesn't give me a very bright picture. Also, it takes a few hours before the raytrace reaches a point that I can tell what it will look like. Is there any way to speed up the process?

Any advice would be helpful.

Thanks,
Zach
