# 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](https://discord.gg/zVvsE9mEEa) - please join if you want discuss use of these tools!

If you are an UE game developer, and want to know how these tools can be used to mod your games, please see the [developer guide](https://buckminsterfullerene02.github.io/dev-guide/).

Any category is not ordered by any means, and any tool that is not listed here, but should be, please submit a PR.

Some of these tools may be unmaintained and/or outdated, but are still useful for people writing their own tools and may want to see how others implemented their tools.

The tag **[CU]** before a tool means that it is **C**ommonly **U**sed by multiple UE modding communities, so is highly recommended for personal use.

The tag **[PW]** before a tool means that it is **P**ay**w**alled.

# Guides
Guides that are useful for modding UE games.

## General
* [Setting up UE as git merge tool for BPs](https://gist.github.com/Panakotta00/c90d1017b89b4853e8b97d13501b2e62) - Written by **Panakotta00**

    - Some very thorough documentation on UE4 Networking for both BP and C++
* [Blueprints vs C++](https://www.youtube.com/watch?v=VMZftEVDuCE)
    - If you do BP modding and haven't watched this video for whatever reason, I highly recommend watching it
    - Complimentary article: [Blueprints vs C++](http://awforsythe.com/unreal/blueprints_vs_cpp/)
* [Amazing YT Channel for BP Tutorials](https://www.youtube.com/channel/UCOVfF7PfLbRdVEm0hONTrNQ)

## 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. 

* [Moolah Modding](https://moolah.dev/docs) (Payday 3)
* [Palworld](https://pwmodding.wiki/)
* [Hogwarts Legacy](https://modding.wiki/en/hogwartslegacy)
    - Contains many useful mod examples using the UE4SS Lua API
* [Satisfactory](https://docs.ficsit.app/satisfactory-modding/latest/index.html)
    - The Satisfactory Modding Documentation is much more useful than official UE documentation in some places, like in the C++ and Blueprint section

## Game Specific BUT Transferrable
These are loose files/sites.

* [How to Package .ucas files](https://github.com/narknon/CCFF7RUproj#to-pak-files-as-ucasutoc)
    - While this guide is for Final Fantasy 7 Remake, it is still useful for modding a UE game that also uses .ucas files
* [Modding Windows Store Games](https://docs.google.com/document/d/1MWazakhAcey7mQlwZEJA-8dDQ-a2KXd-AXa8c0J0Tlo/edit)
    - This guide to get started with modding Windows Store (Xbox Game Pass and similar) UE games versions was created for Deep Rock Galactic but is potentially useful for any other game within this category
* [Astroneer Modding Guide](https://docs.google.com/document/d/193p6thlTOWffF-JIeTGrLUHg9Um5i6gwMJaK4kzy9Ik/edit)
    - The Astroneer Modder's Guide has some nice in-depth explanation of using the UnrealPak and UAssetGUI tools. If you ignore the Astroneer-specific parts, this is definitely relevant to most other UE4 games
* [Hex Editing Materials with HxD](https://docs.google.com/document/d/1JFGoev79Pqvh1JYYua2Ngo3rLRIWu8BeTtrwPWdn6lM/edit#heading=h.ga0funqkacr2)
    - Although this guide was created for Guilty Gear Strive, it features some absolutely brilliant explanations of using FModel and hex editing materials with HxD
* [Ghostrunner Guides](https://github.com/Dmgvol/GR_Guides) - Written by **Dmgvol**
    - A collection of modding guides for Ghostrunner but the same principles apply for all UE4 games
    - Guides like texture and model swapping, hex, UAssetGUI/API, CustomModLoader examples and more
* [Running UE Tools in Linux](https://mod.io/g/drg/r/drg-modding-tools-linux) - Written by **Keplyx**
    - How to run various modding tools in Linux, e.g. UAssetGUI, UModel, UE4 (without building from source)
    - This guide was made for DRG, however most of it is completely UE4 game-generic
* [How to Blueprint Mod](https://mod.io/g/drg/r/how-to-blueprint-mod) - Written by **Buckminsterfullerene**
    - Although this is made for Deep Rock Galactic, it is definitely still relevant for making BP mods for any other game
    - You will have to tailor the blueprint loading method to whatever your game uses, or UML, or whatever, since DRG has a native system implemented by the developers
    - It also features some nice tips for general UE4 use
* [How to Audio Mod](https://mod.io/g/drg/r/drg-mods-a-comprehensive-guide-to-audio-modding) - Written by **Buckminsterfullerene**
    - Although this is made for Deep Rock Galactic, it is definitely still relevant for making audio mods for any other game that uses the default UE audio system
    - It also features some nice tips for general UE4 use

# 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](https://github.com/UE4SS-RE/RE-UE4SS) and the [Game Project Generator](https://github.com/Buckminsterfullerene02/UE4GameProjectGenerator).

# Game Specific Modkits
These modkits are fully reconstructed/decooked game assets that are placed into the editor on top of the game's template project. These modkits completely eliminate the need to manually dummy any game assets for blueprint mods.

They are all generated using [UEAssetToolkitGenerator](https://github.com/LongerWarrior/UEAssetToolkitGenerator) and [UEAssetToolkit](https://github.com/Buckminsterfullerene02/UEAssetToolkit-Fixes) as well as a few automation scripts such as the CUE4Parse anim export script & zain's Blender mass psk/psa -> fbx exporter.
