AnimeStudio is a Windows desktop application for extracting, previewing, and exporting assets from Unity-based games, with a strong focus on miHoYo/HoYoverse titles (Genshin Impact, Honkai: Star Rail, Zenless Zone Zero) and other encrypted Unity games. It provides both a graphical interface (WinForms) and a command-line interface for batch operations. The application parses Unity serialized files (assets, bundles, web files) using a custom binary reader with version-conditional field parsing, supports multiple compression formats (LZ4, Brotli, LZMA, Oodle), and handles game-specific encryption (XOR, AES, custom algorithms). Exported assets include textures, meshes, animations, audio, shaders, and text assets, with FBX export for 3D models and animation clips via a native C++ FBX wrapper. The codebase is a fork/continuation of AssetStudio and Studio, incorporating reverse-engineered format knowledge and vendored native libraries for animation decompression (multiple variants of the Animation Compression Library), Oodle-like decompression (Ooz), and HLSL decompilation (based on 3Dmigoto). The architecture is a .NET 9/10 desktop application with several native C++ DLLs loaded via P/Invoke, and a build script that packages both GUI and CLI into a single distribution.
