Hello guys,
I’m on a pretty big project and I got a problem with my Build.
At 66% the build stop and say Swarm kickoff…
I have renamed all my duplicate name of materials of mesh, I delete all my light in the levels and stop bitdefender to be sure that is not my problem but I just can’t see the real problem… in swarm that’s my message error in log:
[Interface:OpenChannel] Error: System.IO.IOException: Le processus ne peut pas accéder au fichier ‘C:\Users\Gigga-Bijou\AppData\Local\UnrealEngine\4.10\Saved\Swarm\SwarmCache\AgentStagingArea\8487AD2E5DBA413C81373D29B2915895.2E7EF8C34C57539A8BFDE6862A095087.mtrlgz’, car il est en cours d’utilisation par un autre processus.
