Epic's GPUlightmass

I said Yes, but now I recall that in my 5.3 project I said No. Maybe that’s what’s causing lightmaps issue in 5.3 ?

This looks similar to the issue I was dealing with a while ago. See Epic's GPUlightmass - #479 by Ozykz

I had to create a custom engine version with fixes backported from 5.4 (ue5-main branch on github) in order to resolve it. anything newer than 5.1 is essentially a no go for GPULM.
