Swarm Failing to Kick Off

Hey guys, we’re having severe issues with swarm. We’re using 3 computers networked together to build lighting at on the same project, swarm is failing to kick off on all 3.

We have the DDC on a NAS drive also networked to the computers so that projects open faster on all machines. We thought this may have been the issue but have disconnected it and swarm is still failing to kick off.

  • We’ve renamed everything in the project (No duplicate mesh or material names)

  • We’ve tried removing meshes to the point where the lighting will build and then adding them back in causes it to fail.

We’ve also tried everything in this guide - A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums

Any help would be massively appreciated!
