NVIDIA exposes RTX with a Vulkan extension, Khronos claims they are also working on Vulkan-OpenCL interoperability. When it is available and supported by NVIDIA, we can support RTX by replacing the ray/triangles intersection OpenCL kernel with a Vulkan kernel (i.e. it is about replacing a single ...

The sample size is very wrong, I guess I forgot to update the value, it should 4 (unable to check the code at the moment). It is the number of samples required for each path vertex and +3 suggests it uses 4 values at the moment.


Thank you, alpistinho & Dade!
I'll use my own fix for now and wait ...

May be not, can you provide a way to reproduce the problem ? Something like a small python script with a test scene ?


I tried to simplify my scene that day, but it seems that easy scenes don't crash... and then I was getting very busy...

Today I debugged luxcore with my scene and found the ...

Ok! But currently our scenes are big. I'll try to simplify it or make an artificial scene while still reproducing the issue. Please wait a moment.

Are you using border rendering ?

P.S. but are you using Blender or directly LuxCore ?


Thanks! But what is border rendering? I'm using a program which generates a .scn/.cfg pair and then launch "pyluxcoretool.exe console foo.cfg" with std::system()

And I don't know what do you mean by "run a ...

Is anyone experiencing PATHOCL crashes after seeing "PhotonGI evaluating best radius"? When manual testing, this happends occasionally, and re-run luxcore with the SAME scene usually fixed the problem. But now I'm running scripts to run luxcore automatically (i.e. batch rendering), this crash ...

Thanks! It works now.

Thanks! The results (luxcore vs VRay) matched now.

Also, if I defined an "ALBEDO" output, but don't have an "AVG_SHADING_NORMAL" output defined, ALBEDO won't be saved. If I defined both, both will be saved. It looks like a bug? (I'm not using OIDN in this case)

Another question: can we store OBJECT_ID AOV in an exr? I'm getting this error:

RuntimeError: Object ID image can be saved only in non HDR formats: 4

But in wiki (https://wiki.luxcorerender.org/LuxCore_SDL_Reference_Manual_v2.2#Film_Outputs_.28aka_AOVs.29) OBJECT_ID is marked as "HDR".

And with ...
