HDRi and Light Tracing

Check the number of native threads you have in OpenCL, it must be > zero. It renders fine here.

I tested it here (win10, Bl2.81, Lux 2.4 daily from ~3 days ago) and it works fine. I downloaded you scene, rendered directly (CPU), switched to OpenCL setting, rendered again.

How about the OpenCL/GPU drivers? This wasn't mentioned in this thread yet, and dirver problems have occured in the past.

Ryzen 5 2400g
Radeon Rx570
Radeon Software 20.2.1

I'll update and test again tomorrow

Tested and confirmed - working fine w/o any visual difference in CPU vs OCL rendered images (even when using ACES color management).
