UAssetAPI
UAssetAPI is a low-level .NET library for reading and writing Unreal Engine game assets.
<img src="https://i.imgur.com/GZbr93m.png" align="center">Features
- Low-level read/write capability for a wide variety of cooked and uncooked .uasset files from ~4.13 to 5.3
- Support for more than 100 property types and 12 export types
- Support for JSON export and import to a proprietary format that maintains binary equality
- Support for reading and writing raw Kismet (blueprint) bytecode
- Reading capability for the unofficial .usmap format to parse ambiguous and unversioned properties
- Robust fail-safes for many properties and exports that fail serialization
- Automatic reflection for new property types in other loaded assemblies
Usage
To get started using UAssetAPI, first build the API using the Build Instructions guide and learn how to perform basic operations on your cooked .uasset files using the Basic Usage guide.
UAssetGUI, a graphical wrapper around UAssetAPI which allows you to directly view and modify game assets by hand, is also available and can be downloaded for free on GitHub at https://github.com/atenfyr/UAssetGUI/releases.
Contributing
All contributions, whether through pull requests or issues, that you may make are greatly appreciated.
I am particularly interested in .uasset files that have their VerifyBinaryEquality() method return false (or display "failed to maintain binary equality" within UAssetGUI); if you encounter such an asset, feel free to submit an issue here with a copy of the asset in question along with the name of the game and the Unreal version that it was cooked with.
