I’m a mac user and for some reason my Building Lighting is stuck at 0%. I’m not sure how to fix this, I’ve tried to clear the cache and change the quality of my render but it is not working. Help please!!!
Try checking plugins - I had this issue and solved it by enabling UDP Messaging plugin that I’d disabled cause I thought it wasn’t important, turns out it was!
Same experience here.
If enabling UDP Messaging plugin does not work, it might be the firewall blocking “UnrealLightmass”.
It is located in UE4installpath/Engine/Binaries/Mac/. UnrealLightmass needs permission in the Mac’s system settings.
