Universal Settings scene.

Yea BF is not an option. Takes too long even with universal settings.

That's a pretty interesting thought. Rockin, have you done this?

It'd be fun to experiment with - but right now it would be hard to know exactly what's going on without a DMCSampleRate element that can show whats going on with the DMC Sampling for your lights / gi / materials / etc. I was hoping V-Ray 3.0 would have it, but i'm still waiting for it. I suppose you could look at the render logs to see how many rays were fired. I'll play around with it and let you know.
