I didn't understand all of that, but fantastic news! Thanks so much for looking into this stuff.

Any news on this issue yet?

It's the same test scene I uploaded in the original post, but here it is again.

Great, I think I understand what was happening with the caustics pass now. Thanks for clarifying, and for pretty much fixing it to solve any confusion in the future! I still have the problem with the indirect specular pass, however. and the plot has thickened. Here are a few comparison images to bet...

Ahhh, very interesting! Switching the filter to "None" did the trick, and I can now use the Denoise node in the compositor on the caustics pass...thanks so much!! Still very odd though, that it worked just fine in version 2.4 and not in 2.5...is it supposed to work as it is now, or is that...

Has there been any progress with these issues?

In playing around with a recent build of 2.5, I was happy to discover that there's now a caustics pass option (I had been extracting it myself for separate denoising by subtracting all other passes from the main rendered image). Unfortunately, this has revealed some problems with 2.5... Firstly, for...

Yeah, I'm aware of the method of setting the cpu to 100% light tracing, but that requires doing a separate render, which isn't so convenient. What my node group does is is takes the combination of rendered passes and subtracts it from the original rendered result, leaving me with everything else (wh...

Hey all, just for fun yesterday, I made a quick scene to test out underwater caustics and volume effects and came up with this result. underwater_graded_v2.png I'm wondering if there's a way to render out a pass for the volume, like cycles and most other renderers have. (Side note: It'd be cool if t...

Okay, well for anyone having issues in the future, it turns out you need lots of geo to avoid the faceted look, and to solve the inevitable pinching effect you're going to get with subsurf, make a containment loop around the center loop, then shrink them both waaaay down so the pinching isn't as vis...
