Hello, does anyone know how to interact with DLC after Unreal 5 changed the packaging system from just a .PAK file to a small .PAK file along side a new large .UCAS file accompanied with a .UTOC file? I have an app on UE4 with a working DLC system and on UE5 it is now different. I have read online …

It’s not changed. It’s extended. To get back to a single pak, untick the use io store in project settings.
