Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Lighting build failed(Open Job Null, Light data Exporting failed)


I wanna do light build, but it is always failed in my company computer.

Im already do Proxy Test but its not. and Port 5222 is opened(Firewall)

but, when i do light build, in swarm agent log, i always see this log

[Interface:OpenJob] Error: value should not be NULL.

and i think, light data exporting cant success. i think this is the reason.

when i do this one in my home, in folder C:\Users{myname}\AppData\Local\UnrealEngine\4.21\Saved\Swarm\SwarmCache\Jobs\Job-0DED04D8-4895E3C7-1262BF8A-7CFA0828 there are UnrealLightmass and lots of lightmaps (after light build, the name of this change v1.0000000000000000000000000000000B like this)

but , when i do in my office, this folder is always empty. i think between Launcher(im already do this one with unreal engine with github soource) lighmass and swarm.

is there any good idea to resolve this problem?
