This tool helps to automatically patch conflicts between mods for The Elder Scrolls III: Morrowind. It is a replacement for old object merging utilities, as well as Wrye Mash's mashed patch and tes3cmd's multipatch feature.

This program includes an INI file to allow customization. Check TES3Merge.ini for details on object blacklisting/whitelisting, debug options, and object type toggles.

TES3Merge requires the .NET 6 Runtime.

Usage
Extract the TES3Merge folder into the Morrowind installation directory. It can work outside this directory, but when managing multiple installs, it will always look to the parent directory first to find Morrowind.

Simply run TES3Merge.exe, then activate the new Merged Objects.esp file.

If running a Russian, Polish, or Japanese install, see TES3Merge.ini to specify file encoding.

Additional command line parameter options are available, detailed on the GitHub page. The default behavior of TES3Merge is equivalent to:TES3Merge.exe multipatch verify --patches all

Further Details
As an example, Patch for Purists fixes the Expensive Skirt's name, while Better Clothes provides alternative appearances. If you use the two mods together, the changes from one mod will be ignored. With object merging, the changes that both mods make can make it into the game. The following image demonstrates the resolved conflict:

Currently, TES3Merge supports the following record types: Activator, Alchemy, Apparatus, Armor, Birthsign, Body Part, Book, Cell, Class*, Clothing, Container, Creature, Door, Enchantment, Game Setting, Ingredient, Leveled Creature, Leveled Item, Light, Lockpick, Magic Effect, Misc. Item, NPC, Probe, Race*, Repair Tool, Skill, Sound, Sound Generator, Spell, Static, and Weapon. Types marked with a * are incomplete merges, still favoring the last loader for parts it doesn't know how to merge.

Merge rules respect the load order, with the first appearance of the record becoming the base for comparisons. If a later mod modifies the record, its changes will be preserved. Another mod after that will only have its changes made if they differ from the base record.
