Blueprint Open Listen Server

Hello everyone.

I have created a mainMenu for my game, now i need to know how to launch my map as listen server?
As Client it is “open IP” but how to launch a listen server.
I know “game.exe map?listen” but only “map?listen” dont work.


Just replace ‘mapname’ with the name of your level you would like to open, and instead of pressing ‘F’, change it to something like a button click within a UMG widget.
