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, make sure -fileopenlog is in your launch options - without it most .pak mods
won’t load. See PAYDAY 3 for details.
Launch without mods
Section titled “Launch without mods”Click the dropdown arrow next to Launch and select Launch without mods. Modrex temporarily backs up the active game’s mod folders so the game starts without Modrex-managed mods.
When the game 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.
