UABEA
What it is
UABEA is a free, MIT-licensed reader and writer for Unity Asset Bundles and Serialized Files on Windows and Linux. Its maker positions it for modding and research rather than general asset extraction. Supported material includes textures, TextAssets, fonts, audio, and MonoBehaviours, with batch extraction and archive repacking. It also handles Unity Addressables bundles, although editing those requires clearing CRC checks with a CRC cleaning tool. The newer UABEANext version adds docking and multi-bundle opening but is described as a work in progress. The latest listed release requires .NET Runtime 6.0. Windows additionally needs the Visual C++ Redistributable; Linux requires glibc 2.29 or later, and users of musl-based distributions need to compile the software themselves. Font import and export supports TTF and OTF, while font atlases are unsupported. Switch textures can be edited when swizzled, but newly added textures are not swizzled automatically. Windows and Linux nightly builds are linked for both versions.
For and against
For
- Free and MIT licensed
- Reads and writes Unity file formats
- Batch extraction and archive repacking
- Windows and Linux builds
- Supports TTF and OTF fonts
Against
- Addressables editing needs CRC cleaning
- UABEANext remains a work in progress
- Linux requires glibc 2.29 or later
- Font atlases are unsupported
The verdict
UABEA offers broad Unity file handling at no cost, with tools for extraction and repacking. Its runtime requirements and format-specific limitations should be checked before installation or editing.
Who it suits
UABEA suits modders and researchers working with Unity asset files on Windows or Linux. It is less suited to users seeking a general-purpose asset extraction tool.
