Not sure if there are any caustics.
Getting dark areas underneath the rings.
Hmm, that is weird/interesting! Can you attach a scene?
Here is the blend file :
Using Radeon Prorender Version: 2.0.112
Using Blender v.2.80.75
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.
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.
