What UABEA is

UABEA is a free reader and writer for Unity Asset Bundles and Serialized Files, intended for modding and research rather than asset extraction. Supported asset types include textures, TextAssets, fonts, audio and MonoBehaviours. The tool also supports batch extraction and archive repacking. Addressables bundles are supported, but editing them requires clearing CRC checks with a CRC cleaning tool. UABEANext adds docking and the ability to open multiple bundles, though it remains a work in progress. The latest listed release requires .NET Runtime 6.0. Windows users also need the Visual C++ Redistributable; Linux requires glibc 2.29 or later, and users of distributions such as musl need to compile UABEA themselves. Font import and export supports TTF and OTF, but not font atlases. Switch textures can be edited when swizzled, but newly added textures are not swizzled automatically. The repository identifies UABEA as MIT licensed, with Windows and Linux nightly builds linked for both UABEA and UABEANext.
