Use the BuildAssetBundleOptions.ChunkBasedCompression value when building AssetBundles to force LZ4(HC) compression. This is the compression method that Unity uses in both of its AssetBundle caches. If Unity needs to access an Asset from an LZ4 archive, it only needs to decompress and read the chunks that contain bytes of the requested Asset. LZ4 compression is a chunk-based compression algorithm. This is the preferred format for AssetBundles downloaded from a Content Delivery Network (CDN), because the file sizes are smaller than those with LZ4 compression. This compression format is a stream of data representing the entire AssetBundle, which means that if you need to read an Asset from these archives, you must decompress the entire stream. Unity’s AssetBundle build pipeline creates AssetBundles with LZMA compression. This section describes both compression formats. AssetBundle compression formatsīy default, Unity creates AssetBundles with LZMA compression, and caches them with LZ4 compression. See in Glossary formats and cache types that Unity supports. See Texture Compression, Animation Compression, Audio Compression, Build Compression. Run disunity with the -h parameter for further usage.Use this page to learn about the AssetBundle compression A method of storing data that reduces the amount of storage space it requires. Lists all asset objects in a tabular form. Lists all files contained in asset bundles.Īttempts to split an asset file into multiple smaller asset files.
Injects files previously extracted with the bundle-extract back into the asset bundle. Outputs class usage statistics for asset files.Įxtracts all packed files from asset bundles. Outputs various information about assets and asset bundle files. The database is required to deserialize standalone asset files, which usually don't contain any structure information. Learns the structure information from the submitted files and stores any new structs in the database file structdb.dat. Like extract-txt, but just for the structure information.
Like dump, but writes the output to text files instead of the console. Could be useful for manual extraction if extract doesn't support the wanted asset type. See SUPPORT.md for a list of supported asset types.Įxtracts raw serialized object data. Like dump, but just for the structure information.Įxtracts asset objects to regular files (.txt. Available commands CommandĬonverts binary object data to human-readable plain text, similar to the binary2text tool shipped with the Unity editor. In case the launch script fails, try java -jar disunity.jar. Note: depending on the platform, you may need to run disunity.bat (Windows) or disunity.sh (Linux/MacOS).
