ME3Tweaks Mod Manager

ME3Tweaks Mod Manager is a mod manager that supports all three Mass Effect trilogy games, as well as all three legendary versions of the games, plus the Legendary Edition launcher. This program is designed to make it easier to install mods for the Mass Effect series for end users. It has tools for developers, as well as advanced game diagnostic features that can be used to troubleshoot both the program itself and games.

ME3Tweaks Mod Manager is also known as M3.

How to install a mod

• []Make a game backup before you install any mods (in the Backup & Restore menu) DO NOT SKIP THIS STEP

  []Drag and drop your mod download onto the interface (or use Download with Manager feature on NexusMods)

  []Click Import to import the mod into the library (this allows update detection for opted-in mods and other features)

  []Select the mod and click Apply

You don't need to run the game through Mod Manager. But for Legendary Edition games, you can turn on the autoboot option in the settings to automatically boot the selected game when launching it from Mod Manager.

How to remove a mod or restore the game

If you made a game backup:

• []You can restore granularly (enable/disable/delete DLC mods, restore specific files) by clicking 'Manage Target'. Note that texture modded games will have limitations on restoration due to how texture modding modifies the game.

  []You can mirror your backup onto your game by using the Restore menu item at the top of the main window. This will make your game match your backup directory.

  If you didn't make a game backup:

  • []Unfortunately your only option to reliably reset the game is to delete the entire game directory

    and redownload it from EA App or Steam or other online storefront.

    Repairing or uninstalling/reinstalling will not work as it does not remove extra files added by various mods

  Manually copying your game backup will likely result in Mod Manager not recognizing your game, as it has a 'cmm_vanilla' file that is used to force Mod Manager to reject it as a modding target.

  Note that texture mods cannot be 'uninstalled', simply due to how the game engine works.

  Mod installation order

  Mods need to be installed in a specific order in order to properly work.

  • []Content mods - M3 installs these.

    [*]Textures (.mem files) - These must be installed after all content mods or the texture map will become desynced. Textures can be installed in M3 via the Batch Installer feature (to ensure installation order), or through Mass Effect Modder (available in the
