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"

Steam Overlay not appearing

With the Online Subsystem Steam Plugin enabled, and DefaultEngine.ini updated with code, my team is still having an issue with Steam Overlay. It won't work; we tried it in two other projects, one is a blank C++ project, and another is the Demo project for the Infinite Ocean System Plugin. Those two worked, so I used the blank C++ project as a base and made the main project's plugin's the same and DefaultEngine.ini too.

No success, so I tried removing the DefaultEngine.ini and having UE4 make a new one, no success either.

I have been following this (How to Setup Steam Multiplayer... ) tutorial, and am almost done, but if the Steam Overlay won't appear, it doesn't help me at all.

Here is the code inside the DefaultEngine.ini for the two working projects and the Main project.


The "GameName" has a valid name, but is omitted for privacy. It is named like so "BigsmallBigBigBig", it is a lengthy title name, in case that is necessary to know. ( 27 characters )

Best regards,


Product Version: UE 4.15

I got it to work, here is my updated config

[/Script/Engine.GameEngine] !NetDriverDefinitions=ClearArray +NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="/Script/OnlineSubsystemSteam.SteamNetDriver",DriverClassNameFallback="/Script/OnlineSubsystemUtils.IpNetDriver") [OnlineSubsystem] DefaultPlatformService=Steam PollingIntervalInMs=20 [OnlineSubsystemSteam] bEnabled=true SteamDevAppId=480 GameServerQueryPort=27015 bRelaunchInSteam=false GameVersion= bVACEnabled=1 bAllowP2PPacketRelay=true P2PConnectionTimeout=90 [/Script/OnlineSubsystemSteam.SteamNetDriver] NetConnectionClassName="/Script/OnlineSubsystemSteam.SteamNetConnection" [Core.Log] LogOnline=All LogOnlineGame=All [URL] GameName=OmittedGameNameThats27CharactersLong

I believe the fix involved editing my .cpp file for the project along with the above. I got it working around 5 days to a month later.

Your config looks correct.

Are you playing in editor? Or stand-alone?

Steam won't pop up unless you play stand-alone.
