Any attempt to render with LuxCore within Blender 2.83.4 fails with the following error:

ERROR: OpenCL driver API error (code: -30, file:/home/vsts/work/1/s/LinuxCompile/LuxCore/src/luxrays/utils/ocl.cpp, line: 178): CL_INVALID_VALUE

Steps to reproduce:

  1. Open blender on a computer with above specs
  2. Enable LuxRender

Is your OpenCL installation working ? Try to run LuxMark, if it doesn't work, the problem is there.

You have 2 OpenCL platforms installed:

[LuxRays][7.856] OpenCL Platform 0: Clover
[LuxRays][7.856] OpenCL Platform 1: AMD Accelerated Parallel Processing

Do you have something like Pocl installed side by side with AMD OpenCL ?

P.S. running "clinfo" command can help you to track what OpenCL platforms and devices you have installed.

The issue or a similar issue was present in other LuxCore based renderers, but after reinstalling my OS it was resolved. I believe the problem was caused by a faulty driver install. I have not been able to replicate the issue since.

Hi, I have some problem with luxcore 2.5. Then I open Edit > Preferences > Add-ons > search luxcore > In the Film Device: Choose CPU.
