Ok... I've kindof not setup something correctly with my lighting here. Doing lights for mental ray rendering always seems to throw everything out..

I've put a single spotlight in this scene. Decay is set to quadratic. Intensity to 1. It has caustics, gi, final gathering and raytraced shadows on.

It's representative of a problem I have frequently where I get bright patches in the corners where shadows usually gather.

Any help would be greatly appreciated.. I'm sure it's something exceedingly simple which I will not outlive for a long time coming.

cheers,

I havent gotten to use mental ray yet, but thos bright patches looked like they were made by the caustics. Is the setting for the brightness of the caustics seperate from the intensity of the light?

Oh, and how long did it take to render?

yeah - it's come up properly on this one. Though on furniture I've made before I've gotten huge glows in the corners between cushions etc. - though I think I've figured out what that is from.. I had the light with no decay then....

That took 8 minutes to render, but that's network rendered on 5 1700+ Athlon XPs.. (5 includes the machine I was working on)

Hello,
I have one question:
Why the raytracing shadows are opaques when you enable caustics?
I don't understand it.
Thank you very much.
