A mod loader for loading UMM mods

About this mod Author’s original text

UMM

This is a fork of Unity Mod Manager with a few minor tweaks to better support a standalone installation via r2modman or other compatible mod managers.

Note: This version of UMM does not provide a program for installing mods or UMM itself. To install UMM or UMM mods, you must use r2modman or another compatible mod manager.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide.
