I might have found a bug:
I also observed that fireflies don't disappear when I disable specular visibility in the lamp properties.

Re: Hybrid Back/Forward path tracing (aka BiDir without MIS)

Glossy caustics didn't work for me either in Blender, so I went after it, and it seems, that it dosen't work without the "path.hybridbackforward.glossinessthreshold" parameter. - Didn't work in Blender - I exported the scene from Blender => didn't work in LuxCore UI - I added "path.hybridbackforwar...

first light traced

First try with PathOCL + light tracing + PGI persistent indirect cache + OIDN. 220 samples, 1.5min/frame with Ryzen 2700X + RTX 2070. Motion blur didn't work yet with light tracing, so I doubled the frame rate with DaVinci Resolve. Persistent indirect cache and light tracing fit together perfectly ...

Re: Hybrid Back/Forward path tracing (aka BiDir without MIS)

Have started an animation, but when motion blur is activated light tracing does not work :?

I added the support for rendering glossy caustics.
Thanks guys, great progress!
I could not get glossy caustics from Blender, so this feature is yet to be exposed?

Re: Hybrid Back/Forward path tracing (aka BiDir without MIS)

unlike BiDir no caustics are rendered in the water. Like BiDir, no caustics are rendered in the water ... are you getting under water caustics out of BiDir ? Under water caustics are the very same definition of SDS paths. I assume you were talking of PGI caustic cache, not BiDir. Nope, BiDir and Pa...

Re: Hybrid Back/Forward path tracing (aka BiDir without MIS)

I rendered a quick animation with it: 90 frames with 40 sec rendertime per frame. https://youtu.be/MXKYdekMgSE Cool! The solution is a fully functional BiDirVM, something that can now happen but not in v2.2, we need to stop and release v2.2 or is never going to be finished if we continue to add fea...

Re: playing with caustics

I think I have not tested this combination either :oops:
My experience, in architectural settings with PathOCL is like what @FarbigeWelt describes here.

Once the current caustics craze is over, I will investigate the OIDN-with-volumes topic further :D

Have you experimented with PGI caustic cache and volumes? I mean the light rays in the fog/smoke type? I can't get good results.
Thanks!

I have not yet tested caustic cache with scattering volumes.
OIDN does not work well with scattering yet, so I do this kind of work still in Cycles.

Re: Hybrid Back/Forward path tracing (aka BiDir without MIS)

Holy shit this thing is fast!! Wallpaper scene is nearly clean in two minutes, probably OIDN ready in one! Including dispersion! Screenshot.jpg But (nearly) no SDS-paths is a problem for me, especially since we now have a solution for this since three days with periodic caustic cache. I understand t...
