This project aims to fix vanilla meshes by optimizing them, improving performance significantly and eliminating most bugs and errors with vanilla meshes.

Full list of features:
-Alpha Blending has been disabled in favor of Alpha Testing
-NiTriShapes have been stripped down to a bare minimum to increase performance
-Less bloated mesh structure
-Fixed many shading errors in the original meshes
-New, more accurate collision meshes for trees, rocks, architecture and other objects
-Significant improvements to UV mapping for many meshes
-More improvements

Better Vanilla Textures:

This optional module includes several vanilla textures with fixed alphas and several other changes made specifically for MOP. It also fixes a lot of broken textures and makes textures that were supposed to be seamless actually seamless. This module is highly recommended if you plan on using vanilla textures.

Lake Fjalding Anti-Suck:
This esp-based optional file drastically increases performance around Lake Fjalding by replacing several of the smaller meshes with larger, merged ones. This has no impact on visuals. This module will not work with mods that change Lake Fjalding and is already included in Tomb of the Snow Prince.

Weapon Sheathing Patch:
This module is a compatibility patch between MOP and Weapon Sheathing. This will make weapon sheaths show the fixed MOP weapon meshes instead of the vanilla ones. Make sure to install this after both Weapon Sheathing and MOP.

Chuzei Fix:
Enable this if you are not using Better Bodies to fix neck problems with the Native Chuzei Bonemold Helm.

Graphic Herbalism Patch:
This is a patch for the modern GH version, compatible with both MWSE and OpenMW. Use this patch after Graphic Herbalism.


Feel free to use this mod or any of its assets in your own mods as long as you credit the contributors.


Wrye Mash and MO2:

This mod is packaged as a BAIN archive for ease of use with mod managers. Each module can be installed seperately from within your mod manager of choice, preferably Wrye Mash or Mod Organizer 2.

Manual Installation:

Drop the contents of the individual modules you want to use in your data files folder. Manual installation is not recommended.


This will overwrite meshes you already have installed. Install mods like Vurt's Trees after MOP.

You absolutely should regenerate Distant Land if you use MGE (XE).
Uninstall with your mod manager or delete the files that come with this mod.

Patch for Purists:
An excellent unofficial patch for the game maintained by Half11. Install this patch before anything else on this list.

Project Atlas:
It is recommended that you use MOP together with Project Atlas. Make sure to install Project Atlas after MOP.
