Hi! I have encountered a problem when trying to build lighting in a scene based on the UE4 GitHub source code version, the problem is that when I go to build lighting the swarm fails to kick off, I tried building the lighting in an identical room based on the UE 4.25.3 build and it worked perfectly, I would use this version if it had the hand tracking support for the oculus quest but only the GitHub build has it to my knowledge.
Hi, I have done some more research on the bug and found this fix: Lighting build failed. Swarm failed to kick off - Rendering - Unreal Engine Forums
as said in the linked post, rebuilding the lightmass in VS fixed the issue
