Hey y’all. Dragging my head back to the forums to get some help again haha.
So I recently tried following this tutorial: https://www.youtube.com/watch?v=PVDzjOV2wUg and when trying to do the OSS setup it just didn’t work. I enabled the plugins, configured the DefaultEngine.ini and did everything he did in the video and my steam popup just won’t show. I retried everything and it still didn’t work. He’s my log for the project, can someone smarter than me help please?
Can’t recall exactly, but I don’t think TAB for the Steam popup works until you’ve pushed a build to Steam ( could be wrong there ).
It used to work with standalone, but now I think it only works with a packaged build.
The only stuff I have in DefaultEngine is
[OnlineSubsystem]
DefaultPlatformService=Steam
[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=xxx
SteamAppId=xxx
( Obviously your app IDs )
Here is my DefaultEngine.ini file contents right now:
[/Script/Engine.CollisionProfile]
+Profiles=(Name=“Projectile”,CollisionEnabled=QueryOnly,ObjectTypeName=“Projectile”,CustomResponses=,HelpMessage=“Preset for projectiles”,bCanModify=True)
+DefaultChannelResponses=(Channel=ECC_GameTraceChannel1,Name=“Projectile”,DefaultResponse=ECR_Block,bTraceType=False,bStaticObject=False)
+EditProfiles=(Name=“Trigger”,CustomResponses=((Channel=Projectile, Response=ECR_Ignore)))
[OnlineSubsystem]
DefaultPlatformService=Steam
bHasVoiceEnabled=true
[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=480
bInitServerOnClient=true

I’m sure you can test this without having your game on steam, that’s why 480 is a test game id for steam.
Ok quick update: I got the LogOnline message to appear in my -log for standalone
[2026.09.19-20.11.18:807][ 0]LogOnline: OSS: Creating online subsystem instance for: STEAM
[2026.09.19-20.11.18:807][ 0]LogOnline: Warning: STEAM: Steam API disabled!
[2026.09.19-20.11.18:808][ 0]LogOnline: Display: STEAM: OnlineSubsystemSteam::Shutdown()
this is what im getting. any clue on fixing this?
I solved it! I had to create a shortcut to launch the game and i was missing my steam_api64.dll file. I ended up just copying it from a game on my steam and pasted it into my win64 folder.
If anyone needs additional help with this same issue please dm me on discord!
