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

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 that no more development should be invested into caustic cache and this is fine with me but please let's keep this on board until there is anoth...

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

Actually what I don't understand, is why this hybrid path tracing can't do glossy caustics out of the box, when LightCPU can? Because there is a static fixed partition of tasks: specular caustics are rendered by light paths and glossy caustics are rendered by eye paths. You can literally do 2 spera...

Is it unbiased?
Yes.

Does it do SDS-paths?
It is like BiDir, it can only if the light is intersectable (i.e. it is directly visible, like an area light, not like a point light, etc.). But if the area light is very small, it may be not very good at rendering SDS paths (again, like BiDir).

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

Introduction The current implementation of PhotonGI caustic cache has been stretched up to the point to not make any sense. I'm looking for an alternative solution to replace and discard caustic cache altogether. Hybrid Back/Forward path tracing is what I'm thinking to use at the moment. Hybrid Bac...

Can you post a complete rendering log ?

Does LuxMark show 2xGPUs ? One from AMD and one from Intel ? Intel driver/hardware is not able to run any complex OpenCL kernel, try to use only the AMD GPU.

Re: Transitioning from VRay to LuxCoreRender

Part I. [...] Part II. [...] I wonder whether we can do similar things in luxcore, especially the "generateGI" switch. As general rule, none of the settings you have mentioned in your part #1/#2 exist in LuxCore. This is somewhat a "cultural heritage" of the old LuxRender: we try to aim for a physi...

Attached test scene crashes on first cache update whenever Caustic Cache is enabled.
I should have fixed the problem. You were in a quite specific case where the caustic cache is empty (it is what many "PhotonGI metropolis sampler is unable to find a useful light path" are going to mean).

Great!
I see the build has succeeded but somehow the "latest" category from Github has disappeared and the release has not been deployed :?:
I scheduled another build, Azure isn't very reliable in the latest days.
