I’m watching this tutorial series and I’m creating a blueprint only game on engine version 4.14.3 https://docs.unrealengine.com/latest/INT/Videos/PLZlv_N0_O1gYqSlbGQVKsRg6fpxWndZqZ/abmzWUWxy1U/
At this point he simply launches in standalone game mode with steam UI and the overlay popping up and working Blueprint Multiplayer: Find a Match Graph | 11 | v4.11 Tutorial Series | Unreal Engine - YouTube
It does not do this for me and I did add the lines of code to the DefaultEngine.ini as he stated in the video. I also enabled the online subsystem steam plugin and made sure the steam overlay is working on other games.I thought maybe the engine version was the issue so I tried 4.10 and 4.13 as well and the issue persists(and 4.10 just flat out didn’t work at all and the blueprints were all missing lol).
I did do research before posting this and couldn’t find an answer.
So I think there’s something wrong with steam not knowing about the game launching.
