Does this also mean, you didn't use any caches?
Maybe you used bidir?

Very-very nice renderings by the way, I truly envy your talent.

In Blender 2.81 they improved Cycles behavior: https://wiki.blender.org/wiki/Reference/Release_Notes/2.81/Cycles Adaptive Subdivision Cycles adaptive subdivision now stitches faces to avoid cracks between edges, that may be caused by displacement or different materials. https://wiki.blender.org/w/im...

Light tracing (or the cache) is used only "under" the sphere because the caustic is only there, over the sphere, normal path tracing will be used and your light source is very hard to find for a path tracer: just render with normal path tracing to have an idea. Yes, I know this, and it doesn't real...

If Bidir have to exist it need more love... BiDir must exist (and needs solution for SDS) to be the full featured "holistic" reference renderer. Path Tracing with Light Tracing and PGI caches is good for the most scenes, but it's overly complicated and still doesn't cover complex cases, like when t...

... lighttracing isn't doing anything.

Isn't it because of the path.hybridbackforward.partition setting?
(Just an idea, didn't have much time to test it yet.)

I prefer unbiased solutions, but in this case I think so too, that radius reduction isn't useful.

Are you sure that caustic cache works with volumes?

It didn't seem to me in my scene, so I made a simple test case.

BiDir + metro: PT Sobol + Light Tracing: PT Sobol + Caustic Cache:

No, no, I will still add an option for "use_caustic_cache_only_for_SDS_paths" so you use PATHOCL + Hybrid rendering + SDS Caustic cache to get the best of all modes. From the UI point of view it should be just a combo box in Blender with: 1) path tracing 2) path tracing + light tracing 3) path trac...

Have you changed the photon path max. depth ? The default is something like 4...

This was the solution, thanks!
