Does anybody know if there is a way, at Unreal’s engine level, to prevent from having multiple instances of your application running? I mean, once you have your app packaged, if you try to open multiple times the ‘exe’, the application should only launch the first time. Subsequent times, the only effect should be to gain focus of the unique instance you previously launched.
But is it possible to move the loading phase earlier?
For example, check the file lock before the window popup, so starting second instance won’t see a new blank window.
