DisUnity
An experimental command-line toolset for Unity asset and asset bundle files, mostly designed for extraction.
Download
The latest build can be found on the releases page.
Usage
Note: depending on the platform, you may need to run disunity.bat (Windows) or disunity.sh (Linux/MacOS). In case the launch script fails, try java -jar disunity.jar.
Available commands
dump
Converts binary object data to human-readable plain text, similar to the binary2text tool shipped with the Unity editor.
dump-struct
Like dump, but just for the structure information.
extract
Extracts asset objects to regular files (.txt, .wav, .tga, etc.). See SUPPORT.md for a list of supported asset types.
extract-raw
Extracts raw serialized object data. Could be useful for manual extraction if extract doesn't support the wanted asset type.
extract-txt
Like dump, but writes the output to text files instead of the console.
extract-struct
Like extract-txt, but just for the structure information.
learn
Learns the structure information from the submitted files and stores any new structs in the database file structdb.dat. The database is required to deserialize standalone asset files, which usually don't contain any structure information.
info
Outputs various information about assets and asset bundle files.
info-stats
Outputs class usage statistics for asset files.
bundle-extract
Extracts all packed files from asset bundles.
bundle-inject
Injects files previously extracted with the bundle-extract back into the asset bundle.
bundle-list
Lists all files contained in asset bundles.
split
Attempts to split an asset file into multiple smaller asset files.
list
Lists all asset objects in a tabular form.
Other parameters
Run disunity with the -h parameter for further usage.
Examples
