How to force a certain resolution once packaged?

[IronGuardian921 (IronGuardian92)]

I am working on a 2D game. I want to force a 4:3 aspect ratio (specifically a 1280 x 960 size) and set to borderless windowed mode once packaged. How do I do that? I’m trying to get a more retro feel to the game.

Yes, you can enable Use Borderless Window in your project settings

and then use this in your blueprint

Please note, this will not work on your editor. You must compile your game and run as executable, or right click on your uproject file and use LaunchGame
