Advanced Steam Sessions No Longer Works in UE5

Development Pipeline & Plugins

I have Advanced Sessions/Steam Sessions in my project. Everything was set up properly and worked in 4.27, but after migrating my project to UE5, it no longer works. I updated the plugins to the UE5 versions, all the .ini stuff is set, appid is 480, etc.

Results:
Run from standalone while steam is open: “Failed to initialize game server with steam”
Run from standalone while steam is closed: Works normally
Run in-editor: Works normally

Did something change in 5.0.0 that causes this to no longer work? Am I doing something wrong?

Edit: On a related note, opening two standalone windows now cuts frame rate to like 1 fps, where in 4.27 there was almost no drop in frame rate. Is this something that I can fix or is 5.0 just broken?

No. This is a hard roadblock to my project and cannot find anything on the internet about this.

When you start this project, let it all rebuild etc. and then - with Steam enabled - start the standalone game from the editor (you’ll have to save the shown map): what does happen?

It wont open. Says the Advanced Sessions and Steam Advanced sessions plugins are for a different engine version.

€dit: Usually you are being asked if you want to rebuild them. I will try to upload the whole project from me.

Does this work?

The map opens to a default camera under the ground. Is this meant to test if the steam session works? I don’t see any blueprints in this project that are trying to create a session, or any blueprints at all.

Yes. Test the standalone mode while Steam is running. When this works, you can go on to test a blueprint, or tell me what to add so you can test it or send me your not functioning project :slight_smile:

The steam server started correctly, and I noticed that the create session node looked different from the one in my project. I replaced my plugin files with the ones from your project and now it works

Isn’t the plugin, SteamNetDriver has broken since UE 4.27.2, the only solution is the steam core pro plugin which has its own NetDriver

14

It’s working fine for me in 5.0.3 without steam core pro plugin but not working in 5.1 (I am using launcher binary version though)

I have the same problem, did u fix it?

16

if you are using 5.1 then it dosent work for most people due to issues with latest update so i recommend going back to 5.0
