level size from start menu

hey there, I am looking for a way to set the level / World boundaries or size from the start menu ingame in UE 5. I checked the forum but didn’t find any suitable solution.
Basically the goal here is to set the size of the level where the player spawns, directly from the start menu or change it afterwards in the main menu.
Thank you so much for any help!

Hey there @blueser12! Welcome to the community! Are you intending to set boundaries at runtime ie Invisible walls or destroy zones, or are you intending to handle map generation itself at runtime?
