Launching the game
Launch modded
Section titled “Launch modded”Click Launch in the top bar to start the active game with all enabled mods active. Modrex passes your configured launch options to the game and hands off to your launcher.
For PAYDAY 3, pak mods load only when UE4SS is installed. See PAYDAY 3.
Launch without mods
Section titled “Launch without mods”Click the dropdown arrow next to Launch and select Launch without mods. For Ready or Not, Modrex uses the game’s Safe Mode for Pak mods. It leaves the shared Paks folder in place and keeps movie replacements and INI settings applied. It does not disable manually installed DLLs or scripts.
For other games, Modrex temporarily backs up the managed mod folders.
When a backup-based session closes, Modrex automatically detects this and restores your mods. While a vanilla session may still be running, a banner across the top reminds you mods are hidden and offers a Restore mods button - use it if Modrex closed before it could restore automatically (for example, if the app itself was closed mid-session).
See Launch modes for how target-scoped backups and restore behavior work.
