I have been unable to successfully build lighting in my project for some time. I was forced to move away from the Standard Epic Launcher and run Unreal through Visual Studios from the Github Build in order to try and build UnrealLightmass manually but it has no effect.
Currently the only way to bypass the error is to turn ON ‘Force No Precomputed Lighting’ which unfortunately just bypasses most if not all of my scene lighting properties.
I have tried everything I could find online such as manually building UnrealLightmass, trying new empty projects, removing lights and searching through blueprints for errors but nothing has helped.
I have also seen an error in the Swarm Agent stating “[Interface:OpenJob] Error: Invalid class” but I could not find any sufficient methods for correcting this issue.
Any help on this issue would be exceedingly helpful as I have been stuck entirely on this problem for the last week.
