Hello,
I have a map in which I’m trying to build lighting, however UnrealLightmass stops unexpectedly without any reason (and with any quality). This is the first time it ever happen in my case.
SwarmAgent log:
21:38:44: LogWindows: Warning: CreateProc failed (2) …/…/…/Engine/Binaries/Win64/CrashReportClient.exe “D:/…/AppData/Local/UnrealEngine/4.17/Saved/Swarm/Engine/Programs/UnrealLightmass/Saved/Crashes/_0000” -AppName=UE4-UnrealLightmass -CrashGUID=_0000 -DebugSymbols=…\Engine\Intermediate\Symbols
21:38:44: [Job] Job has failed! Job executable didn’t exit cleanly. Exit code: 1
According to the generated minidump :
Exception Code : 0xC0000005
Exception Information: The thread tried to read from or write to a virtual address for which it does not have the appropriate access.
To avoid issues with privacy I would like to send my crash dump privately to an UE support guy or developer in case it would help.
