📋 About This Mod

An updated version of this mod is available at https://www.nexusmods.com/newvegas/mods/54991/?

I'm sure many have realized that I have not been in the forums of late. I apologize for the falling off of support. I wanted to let everyone know that I won't be supporting this version of FOMM for the next while; however, I am actively working on a replacement that I hope everyone will find far superior. Rest assured that I haven't abandoned everyone, but that I am indeed working to create the best FOMM yet.

I have taken FOMM out of alpha. I'm sure it's not perfect, but I believe it to be sufficiently stable for general use.

This version of FOMM is the first step in expanding the scope of the mod manager. Instead of having two different managers, one for Fallout 3 and another for Fallout: New Vegas, FOMM is able to manage mods for both games from a single install. This ensures that all new features that are added to FOMM will be available for both games. Further, the folders that FOMM uses to store install info and FOMods are now configurable, allowing you to place them wherever you have disk space, rather than wherever FOMM is insalled.

Main Features:

For the mod user:

  • []Fail-Safe Mod Installs

    Don't worry if a mod install fails; FOMM cleans up after itself, preventing half-installed mods.[]Mod Info Retrieval

    When adding new mods, FOMM can retrieve missing information about the mod (such as author and the screenshot) from the web. You are prompted to enable this option, and it can be changed in the settings window.[]Mod Versioning

    FOMM is able to upgrade mods without have to re-activate them, and without changing which mods overwrite which.[]Mod Reactivation

    You can change the installation options of mods without have to reinstall them.

For the mod author and tinkerers:

  • []Configurable Scripts

    Control how your mod can be installed, and give your users choices. You can write powerful install scripts using the flexible XML Configuration scripts, the more powerful C# Scripts, or event the traditional OBMM/OMOD script language.[]Low-Level Editing Tools

    FOMM still includes: TESsnip, BSA Creator/Unpacker, Shader Editor.

Note to Mod Authors:

FOMod scripts for FO:NV mods should derive from FalloutNewVegasBaseScript, instead of BaseScript. The functions in the scripting language have changed to reflect the differences between FO3 and FO:NV (for example, NVSE instead of FOSE). If your scripts don't derive from FalloutNewVegasBaseScript they will still work, but you won't have access to the new functions, and calling FOSE-related functions will cause your script to fail.
