UE Modding Tools

A databank of every modding tool that has potential to be used across multiple UE games. Many tools were submitted by the lovely members of the Unreal Engine Modding Discord - please join if you want discuss use of these tools or just general UE modding!

Note

The tag [CU] before a tool means that it is Commonly Used by multiple UE modding communities, so is recommended for personal use.
The tag [PW] before a tool means that it is Paywalled.

If you are an UE game developer, and want to know how some of these tools are used to mod your games, please refer to the developer guide.

Categories are not ordered by any means, except for CU tools at the top.

Any tool that is not listed here, but should be, please submit a pull request.

Warning

Some of these tools may be unmaintained and/or outdated, but are still useful for people writing their own tools and may want to see how others implemented their tools.

    • Supports importing large scenes, riggable characters, and vertex based animation to Blender, 3DS Max, and Noesis

Guides

Guides that are useful for modding UE games.

Tip

There is also a guides forum channel in the Unreal Engine Modding Discord where you can find more guides/modding tips or share your own.

General

  • [CU] UE Modding Guides - Written by Dmgvol
    • A well-written, simple to follow collection of guides for modding UE games
    • Includes guides on modding textures, models, animations, blueprints, tools, and more

Game Specific Modding Documentation Websites

Many popular modding communities for various games have their own websites for documenting and centralising modding information. In many cases, information can be shared between other games, due to maybe using the same tools, engine version or the game uses similar systems. Usually, games will keep their modding resources exclusively within their own Discord communities, however this lacks the benefit of having their docs indexed and searchable by search engines.

Game Specific BUT Transferrable

These are loose files/sites.

UE Modding Discord Servers

A bunch of links to various UE Modding Discord servers. If you know of any that aren't listed here, please make a PR. Feel free to nick this list of Discord servers for your own Discord.

Warning

Although I have tried my best to get permanent invite links, I am not responsible for any being invalid.

Game Specific

Game Specific Template Projects

These are "mirrored" C++ UE projects for various games. They are meant to be used as a base for blueprint modding, and are usually updated to the latest version of the game. They completely eliminate the need to manually dummy any C++ headers.

They are all generated using UE4SS and the Game Project Generator.
