I’m working on UE4 and I would like to know if something has evolved since 2019 around multiplayer?

I tried to use this project: https://docs.unrealengine.com/en-US/Resources/Templates/CollabViewer/index.html

But this doesn’t work…

I would like to know what do you mean by:
“If you want to create a multi-player application it will work on Furioos if the user can join an other user directly from your application.” ?

Thanks 🙂
