GPU lightmapper doesn't work on Radeon RX 5700
Unfortunately the user reports from the Unity forum about the GPU lightmapper not working on RX5700 turned out to be true. The OpenCL compiler issue below is making it fail.
This appears to be a blocking issue for every Unity user with a RX5700.
The failure happens in LoadOpenCLProgramInternal.
-- GPU Progressive lightmapper will use OpenCL device 'gfx1010' from 'Advanced Micro Devices, Inc.'--
use -OpenCL-PlatformAndDeviceIndices <platformIdx> <deviceIdx> or -OpenCL-ForceCPU as command line arguments if you want to select a specific adapter for OpenCL.
