Lighting build failed. Swarm failed to kick off

Hi ,

Is this something that is reproducible for you in a new project? I’ve personally moved projects between multiple machines without this issue.

When moving to other machines what steps have you taken to make sure that Swarm can kick off and build lighting?

  • Did you disable the Firewall and Anti Virus/Malware software?
  • Do these other machines have UE4 installed, and can you create projects on them and build lighting without issue?
  • If you’re using 4.9, does this still happen with 4.10, or have you tested in 4.10?

Thank you!
