Packaging a project with Steam Online Subsystem

Hi,

I’m building an online game. The project right now is nothing more than a menu structure which gets me to the level where the game takes place. Before dipping into Steam, all works spotless when packaging and playing. Now I’m determined to add Steam’s online funcionality to it. Please note that this is a blueprint-only project and no custom code has been implemented. I see people saying “blueprint project” or “c++ project” occasionally, but I don’t know if that’s only an unofficial name for wether or not you added custom programming, but I didn’t add anything other than regular Blueprints.

I started with a Blank project without starter content. I’m running 4.20.3 on a computer with stable internet connection.

Before I started, I packaged the proiect without the Online Subsystem to see if it works. It was spotless.

  • I log in to Steam on my system.
  • I closed the engine,
  • I edited DefaultEngine.ini to contain:

_

[/Script/Engine.GameEngine]
+NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="OnlineSubsystemSteam.SteamNetDriver",DriverClassNameFallback="OnlineSubsystemUtils.IpNetDriver")

[OnlineSubsystem]
DefaultPlatformService=Steam

[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=480

[/Script/OnlineSubsystemSteam.SteamNetDriver]
NetConnectionClassName="OnlineSubsystemSteam.SteamNetConnection"

_

  • I started the engine up again,
    enabled the Plugin “Online Subsystem
    Steam”.
  • I was prompted to restart the
    engine and I did.

After it restarted, I am unable to package the game. Playing it in Standalone, yet Steam doesn’t pop up at all.

There are only few good sources, a bunch of them outdated and a lot of contradictions amongst the things I read and watched. I really hope someone here can help me out.

If you need anything, please ask.

On a side note: The Packaging does give warnings for missing ThirdPersonOverview. This happened from the beginning.

Here’s the Output Log:
