🎯 Tips & Tricks
If you're modding Fallout 3 or New Vegas, FOMM can handle FOMOD installers, but check for compatibility patches with your game version.
Use FOMM's built-in archive invalidation toggle to ensure custom textures show up correctly.
For newer Fallout games, consider using Mod Organizer 2 instead, as FOMM is outdated.
