Nuget Nuget

The Unreal library (UELib) provides you an API to read (parse/deserialize) the contents of Unreal Engine game package files such as .UDK, .UPK. Its main purpose is to decompile the UnrealScript byte-code to its original source-code.

It accomplishes this by reading the necessary Unreal data classes such as:

UObject, UField, UConst, UEnum, UProperty, UStruct, UFunction, UState,
UClass, UTextBuffer, UMetaData, UFont, USound, UPackage

Classes such as UStruct, UState, UClass, and UFunction contain the UnrealScript byte-code which we can deserialize in order to re-construct the byte-codes to its original UnrealScript source.

How to use

To use this library you will need .NET Framework 4.8 (The library will move to .NET 6 or higher at version 2.0)

Install using either:

  • Package Manager:
    Install-Package Eliot.UELib.dll

See usage for further instructions on how to use the library in your project.

If you're looking to modify the library for the sole purpose of modding UE Explorer, I recommend you to clone or fork this repository and install UE Explorer within your UELib/src/bin/Debug/ folder, or change the project's configuration to build inside of the UE Explorer's folder.

Want to try out the latest library release? Then you can simply save Eliot.UELib.dll to the folder where you have installed UE Explorer at. Note that the current release of UE Explorer is using version 1.2.7.1.

Beware, opening an unsupported package could crash your system! Make sure you have saved everything before opening any file!

Note UE3 production-ready packages are often compressed and must first be decompressed, Unreal Package Decompressor by Gildor is a tool that can decompress most packages for you; for some games you need a specialized decompressor, see for example RLUPKTool.
