I'm running Blender 2.8.3 on Ubuntu 18.04. I downloaded BlendLuxCore for Linux 64 bit and followed the instructions to install it as an add-on to Blender.
When I select the LuxCore render engine, set to render with the CPU, it fails to render and I get the following error message:
Error | OpenCL driver API error (code -1001, file:/home/vsts/work/1/s/LinuxCompile/LuxCore/src/luxrays/devices/ocldevice.cpp, line 72): -1001
This is very confusing because as I understand it, OpenCL is analogous to CUDA and is used for GPU computing. Why would this be an issue for CPU rendering? I found an identical issue to my question posted on GitHub, but I don't see how the response there helps. Do I somehow need to set up OpenCL drivers on my computer even if I'm only interested in rendering with my CPU? And if so, why?
In searching for a solution to this, I've seen references to there being different versions of LuxCore for CPU and GPU, but at least for the more recent versions the download page does not make this distinction, and the render properties panel allows you to select either CPU or GPU rendering.
