Luoshuang's GPULightmass

Why didn’t you move to UE4.22 yet ?
UE4.19 was quite early version of GPULM.
Those splotches can be reduced sometimes by using higher values in Baselightmass.ini:
[DevOptions.GPULightmass]
NumPrimaryGISamples=128
NumSecondaryGISamples=128

But I still recommend to move to 4.22 at least and use these values I mentioned above for bake ( in PRODUCTION mode - always ).

I installed 4.22 and I get this error
