Re: Caustics

Hmm, that is weird/interesting!  Can you attach a scene?

Re: Caustics

You have the "ray epsilon" in this scene (in the quality settings) set to 2.  Is there some reason why you did that?  Normally that should be a small value like 0.001 unless you have a huge scene scale.  I think artifacts are related to that.

Re: Caustics

Hey thanks, that fixed the problem. No more dark areas underneath the rings.

I had it set at 2 because when i was working with interiors, I was getting realistic

renders with that setting. Ive been using that ever-since.
