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

I have a scene that represents a common lighting scenario. A row of LED illuminates a volume diffuse, but mostly polished, lens. All this is built in a housing and closed by a clear cover lens. It is frankly a scene to cryptic to analyze without knowing exactly what is supposed to be. Try to reduce...

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

But I do wonder how the sds only caching for caustics will work. will the entries be created by lighttracing only? And then have the opencl use cache entries for sds only? Yes, the cache will be created a pre-processing time like current caustic cache and it will be used only to render the result o...

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

Seems there is still a problem with motion blur. I tried to render the classroom scene with hybrid path, 100% light tracing for testing and encountered a strange result: - caustics seem way too bright - upper half shows a strange, different pattern - with motion blur disabled the render seems ok It...

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

I can't seem to get denoising to play nicely. Sobol with OIDN works, but BCD doesn't show any light tracing. When using random, any denoising causes light tracing to be disabled entirely. Yes, I have probably forgot to add the BCD support to Hybrid. But, sincerely, I don't even know if it is worth ...

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

You have OpenCL enabled, 100% light tracing can be done only with CPU-only rendering, the GPU will still render only eye paths. The "Light rays" setting affects only the CPU threads, not the GPU. For that kind of test, use PATHCPU, not PATHOCL. The original file settings were for animation with Ope...

Re: Transitioning from VRay to LuxCoreRender

Thanks, B.Y.O.B and Dade. Note: PhotonGI doesn't support radiance groups at the moment. ah... Is supporting radiance groups in PhotonGI officially planed? How difficult is it? No good way to do it? Or it can be done, but there may be some penalty/restrictions? Or nothing really difficult, but needs...

Re: LuxCoreRender v2.2beta2 released

:D Well, i didn't went for 16K yet... but did Sharlybg's "Food" Scene with Tiled Sampler, tiled OIDN... all in all roughly 50min @ 10K! on Q M5000 & GTX1070 8-) The only reason I haven't yet removed TILEPATH render engine ... and I want really badly to remove that code, it is literally useless in a...

Dade please. This or portals.

Luxcore definitely needs either this to be working well or a standard "portal" solution
I consider now the work for v2.2 PhotonGI cache and Hybrid rendering done. This is the next (and last) topic for v2.2 (bug fixes aside).
