About AssetStudio
AssetStudio is an open-source tool for exploring, extracting and exporting Unity assets and AssetBundles. It supports Unity versions 3.4 through 2022.3, including 2021.3.10+, 2022.2 and 2022.3, and handles Texture2D, Sprite, AudioClip, Font, Mesh, Shader, VideoClip, MonoBehaviour, Animator and Lua bytecode with format-specific export options.
Loading AssetBundles decompresses them in memory and may use a large amount of memory; the documentation suggests extracting to a folder first. MonoBehaviour reading requires selecting the assembly folder, Il2Cpp projects require dummy DLLs from Il2CppDumper, and Lua decompiling is disabled by default.
