I totally forgot of direct hits on infinite lights, I only fixed area lights, I will apply the same fix to infinite.
Ok, fixed.
Thanks Dade.
When I run the Cornell scene with the default values, there are visible splotchy artefacts around the corners of the small boxes on the ground.
They can be reduced with high photon count and not too small lookup radius but they don't disappear entirely.
I've heard about this problem from other renderers too so I fear there's no easy solution to this?

Is this caustic cache artifact or indirect lighting?

From indirect photon cache.

LuxCoreUI crashes when I try to use rough glass in my caustics file.

Can you upload the scene?

Next step, try to use Kd-tree over BVH, it may be faster.
Nope, tried but no benefits.

So, can be something done about those corner splotches from epilectrolytics's post?
