Launch options
Section titled “Launch options”Most PAYDAY 3 .pak mods require -fileopenlog. Add it in Settings - Launch Options for Steam and Epic Games, or configure it in the launcher if the app cannot write launch options for that launcher.
Priority
Section titled “Priority”For .pak mods, Modrex writes numeric filename prefixes so your visual priority order is reflected on disk. Directory-based UE4SS mods are not renamed for priority.
