Unity Studio is a tool for exploring, extracting and exporting assets from Unity games and apps.

It is the continuation of my Unity Importer script for 3ds Max, and comprises all my research and reverse engineering of Unity file formats. It has been thoroughly tested with Unity builds from most platforms, ranging from Web, PC, Linux, MacOS to Xbox360, PS3, Android and iOS, and it is currently maintained to be compatible with Unity builds from 2.5.0 up to the latest version.

Current features

• Export to FBX, with complete hierarchy, transformations, materials and textures. At the moment, geometry is exported with normals UV coordinates and vertex colors, but no animation data.
• Extraction of assets that can be used as standalone resources:
  • Textures: DDS (Alpha8bpp, ARGB16bpp, RGB24bpp, ARGB32bpp, BGRA32bpp, RGB565, DXT1, DXT5, RGBA16bpp)
  • PVR (PVRTC_RGB2, PVRTC_RGBA2, PVRTC_RGBA4, PVRTC_RGB4, ETC_RGB4)
  • Audio clips: mp3, ogg, wav, xbox wav (including streams from .resS files)
  • Fonts: ttf, otf
  • Text Assets
  • Shaders
• Real-time preview window for the above-mentioned assets
• Diagnostics mode with useful tools for research
