I need to reproduce a very realistic array of SMD LED, many many lights that are passing through a translucent material, I know that's a very difficult scene for a ray tracer. But I think that I will change the whole approach using a mix of Cycles, LuxCore and some compositing trick, I Just need to...

If each light only illuminates a small area, DLSC (direct light sampling cache) could also be interesting for you. It is available in the light strategy dropdown. https://forums.luxcorerender.org/viewtopic.php?f=5&t=430 https://forums.luxcorerender.org/viewtopic.php?f=5&t=675 I've tried but...

update: I downloaded this buid and the bug seems fixed, thank you! the only thing that doesn't work properly with OpenCL is this one, some lights are darker compared to other identical. I don't know how to explain in a better way but if you try to render this scene with OpenCL and CPU and check the ...

I have downloaded luxcorerender-latest-win64-opencl.zip but I still get the same result. If I remove pyluxcore.pyd I get the error as expected and if I restore the file LuxCore works, but always with that bug...

The number of light groups supported in OpenCL is capped to 8 (default+7): https://github.com/LuxCoreRender/LuxCore/blob/2ac2349fb2f3d9fb1bcf6bca35b60859b3143d6e/src/slg/engines/pathoclbase/pathoclbaseoclthreadfilm.cpp#L119 So it should work in your case. Tomorrow, I will check what is going wrong....

Ok, if I disable clamp everything works fine on the scene I uploaded in this thread. But with my project scene the strange behaviour of some emitter that remains dark or with fewer samples is still present. Here there is a simplified version of my project scene, the fewer samples issue in some rando...

Thanks! I'll give it a try, since my scene is very difficult (3000 light sources through tranlucent mat) clamping is not effective at all.

Hi! I'm working on a project and I'm facing a quite big issue for me: I need 6 light group (5 differnt groups and the default one) and if I render with CPU everything is ok, but if I switch to openCL the last group is also visibe in the the default group. Moreover some obejects (group instance) that...
