What it is
AssetStudio is a Windows-style desktop tool for opening Unity asset bundles and game files, looking through what they contain, and exporting pieces such as textures, audio, fonts, meshes and models. People use it to inspect or recover assets from Unity-built projects. The README states it is not affiliated with Unity Technologies. The repository is archived, so it is no longer maintained.
- Open a folder of asset bundles with File-Load folder and browse the asset list
- Export Texture2D files as png, tga, jpeg or bmp
- Export a Mesh as obj or an Animator as FBX with bound AnimationClip
- Export MonoBehaviour data as json, after pointing the tool to the assembly directory
Great for
- Developers who want to inspect the contents of Unity asset bundles
- Modders or researchers looking at textures, audio or models from Unity games they have rights to examine
- People who need to export Texture2D, AudioClip or Mesh files to common formats
- Users working with Unity versions in the listed supported range (3.4 to 2022.1)
Not ideal for
- Anyone needing active support or bug fixes, since the repository is archived and last pushed in December 2022
- Projects using Unity versions newer than 2022.1, which the README does not list as supported
- Users who cannot install .NET runtimes or build tools, since it requires them
- Anyone who wants to use assets in ways that the games' licenses do not allow
How to get it
- 1
Download the app
You'll need: .NET Framework 4.7.2 (for the net472 build) · .NET Desktop Runtime 5.0 (for the net5 build) · .NET Desktop Runtime 6.0 (for the net6 build)
Clone the repository
git clone https://github.com/Perfare/AssetStudio - 2
Run it
- Install the .NET runtime that matches the build you downloaded (net472, net5 or net6)
- Download the matching zip from the latest release v0.16.47 and extract it
- Open the AssetStudio application
- Use File-Load file or File-Load folder to open your assets or asset bundles
- Use the Export menu to save assets to a folder
- 3
Get the most out of it
- Use File-Extract file or File-Extract folder first to decompress asset bundles and reduce memory use, as the README suggests
- For models, use Model-Export selected objects with AnimationClip to include animations
- For MonoBehaviour assets, point the tool to the Managed folder, or to the Il2CppDumper dummy dll folder for Il2Cpp builds
- Check the Features list in the README to confirm your asset types are supported before exporting
Downloads
Strengths
- Covers many common Unity asset types with export options in standard formats
- MIT licensed, so the source can be read, changed and reused under its terms
- Has been widely used, with about 15,590 stars on GitHub
Trade-offs
- Archived and last pushed in December 2022, so newer Unity formats and bugs will not be fixed upstream
- Loading asset bundles directly can use a lot of memory; the README suggests extracting first
