UE Game Audit Tool

Description

After a game update, there's normally no easy way to tell which assets actually changed, or which mods now need republishing as a result. This tool uses CUE4Parse to hash every assets decompressed/decrypted bytes in a game's pak files (.pak/.utoc/.ucas) - so pak compression settings or re-encryption between builds never show up as a false change, only real content does.

Comes as both a desktop GUI and a CLI (for scripting) - same logic either way.

Installation instructions

Download and run the application. The GUI version will automatically open at a help page to guide you through each option within the app. See GitHub page for up-to-date CLI Reference 

Main features

[]Hash & compare game assets - an exact list of added/removed/changed assets between two builds.[/]

[]Hash & compare mods - cross-reference against a game comparison to get a plain "these mods need updating" report. Only inspects file paths, not content, so it's fast and doesn't need the game files at all.[/]

[]Optional native/C++ tracking - hash UE4SS's reconstructed C++/UHT header dumps to catch memory-layout breaks (a UPROPERTY shifting offset) and source-level changes, not just asset changes.[/]

[]Quick Actions - one click to capture a before/after baseline and run every comparison, no manual manifest picking.[/]

[]Scope Rules - classify Paks content as Game/Mod/Ignore (~mods, LogicMods, or custom subfolders) without relying on a specific folder name.[/]

[]Cancel-able - every hash/compare/Quick Action can be cancelled mid-run without corrupting anything.[/]

[]Profiles - save/switch named field sets per game.

Requirements

An Unreal Engine game you want to scan.
