I also think that angle parameter should be hidden and materials should be cached as if no bump was applied. I have switched from using shading normal to geometry normal in PhotonGI. So bump/normal mapping is now ignored. It seems to work fine but it is hard to predict, give it a spin. will try onc...

But wait, I understand that a large radius will leak through geometry like in your example. But I don't understand that in the situation I posted, how do cache entries from sun even end up inside the box? They aren't leak from outside are they? Isn't the sun hitting the floor outside the box ? I as...

If the cache lookup is smaller than wall thickness only then it won't get through. Yes but this is expected, the radius must be smaller of significative geometry features. I mean otherwise you could use a huge radius and render all the scene with just a single cache entry. Just render a single plan...

I tried changing scene scale, model scale, normals, shaders, tesselating mesh, modifying mesh. Changing settings... If the cache lookup is smaller than wall thickness only then it won't get through. In every other situation it will go through mesh near corner if it's directly exposed to light (teste...

New animation. PathOCL, no PGI but OIDN. 200 frames á 3:50min. First attempt was with scattering volume but that took to long, will try that with Cycles again. Then I wanted to slow it down and scale it up but DaVinci Resolve failed me, so it's too fast now. Anyways, even without cache, animating w...

For better illustration I made a 50% render overlay on cache debug. You can see here that bright cache is created from sunlight that is actually going through mesh(skylight does that too) and then it is lighting up the box from inside. This is a matte material if you switch it to glossy the bright c...

Here's an example of cache failing really bad, I don't know what's going on there: EDIT: This was happening before cache filtering, just to let you know it's not related to that. It seems that light is going through mesh, this might be source of other leaks too...?

I also think that angle parameter should be hidden and materials should be cached as if no bump was applied.

Ok, with filtering things start to look very very good. I am impressed.... here's my observation. spikes in cache are no more recognizable as leaks/bleeding/fireflies. And even extremely difficult situation/stresstest (sun+sky+interior+small pool/100K photons, + small cache size/100K photons) won't ...

filtering looks fine. Does it help with spikes in cache or is it not affecting the issue?

Yes, it does, try it.

I'm on my way azure should finish linux soon too.
