I just want to use only Steam overlay not any Steam networking system on UE4 game.

but when i set DefaultPlatformService=Steam on DefaultEngine.ini, a dedicated server build act on a OSS Steam.

it is fine. it is a right process.

but.

why is it a problem?

I can’t connect to a dedicated server when i play game on a PIE.

AGameModeBase::PreLogin() make an error “incompatible\_unique\_net\_id”, when a PIE connect to a OSS Steam dedicated server.

Can’t i test a game on a OSS Steam dedicated server when using a PIE?
