I just installed and tried GPU Lightmass for the first time with 4.21.
Speed and quality are great, but my result is much darker than with the CPU baker. It is as if less GI bounces are computed. I tried increasing the indirect lighting contribution of the lights without any difference in the result. Bounces in the lightmass settings are set to 100.
Also I get a lot of errors in the lightmaps when setting any rectangle light to stationary. Only when setting it to static the bake works fine.

Happens when swarm unloads everything in the memory of your GPU : if you dont have enough, the baker crashes with this error.

Try to increase the FireflyClampingThreshold in the BaseLightmass.ini in the engine\config folder from 10 to 50 or 100. Be aware that since you increase the threshold you might need to increase samples as well to get a clean result.
But I didn´t touch the fireflyClampingThreshold until now, because I didn´t know what it was for.

Luoshuang just thought I'd pop in to say thanks for all your work! GPULightmass is amazin' and I'm using it for everything I don't need HLOD clusters for. Saving me a huge amount of time.

Luoshuang hey ! Awesome work on the 4.21 release, GPULM is a tool we cant work without
I just got this error after trying to bake lights on datasmith model, wonder why it happens on this one only ? (also the first time I see a primitiveCount >0 error)
Cheers !

If it helps someone, just give me a "Like" below.
UPDATE 12/11/2018: Now updated to work with 4.21 (Unified Settings). Allows to chage settings on the fly between different BaseLightmap.ini configurations.
