Failed lighting build on mac in 5.7

[xeldrax-ace]

I go to build and build lighting only, then instantly fails. I get this error: “MapCheck: Error: WorldSettings_1 Maps need lighting rebuilt”. I have assets set to static and have lumen turned off.

I had this problem too, it was that the swarm agent for building light didn’t work. But I could build with the GPU Lightmass plugin (you need to temporary enable Support Hardware Ray Tracing in project settings for this too)

I appreciate all your help. I made the changes you suggested and still having the same error.
