Edit 220325: issue is solved, see Epic's GPUlightmass - #281 by maxbrown
Testing UE 5.0.0.p2 - GPU lightmass still broken. Same result as in the picture in my post above.
Log reports ‘LogTemp: Static lighting system is removed for world…’.
Reported last week, no response back.
Hoping this gets fixed. Lumen is fantastic tech but for VR / Quest the good old lightmaps are still needed.
