Abstract

A small endeavor to automate the import raw action from UABEA: nesrak1/UABEA#47 (comment).

Usage

⚠ You need to have the classdata.tpk next to the executable (can be downloaded from AssetRipper type tree tpk → click the latest workflow run and download uncompressed_file and copy the unzipped file next to the executable and rename it to classdata.tpk).

  --overwrite            Overwrite the input file instead of creating a .patch.

  --by-name              Ignore dat file name and use the asset name instead. If there are multiple assets with the same name, the one with the largest file size will be overwritten.

  --help                 Display this help screen.

  --version              Display version information.

  input-file (pos. 0)    Required. The asset bundle file to patch (e.g. `resources.assets`).

  dat-file (pos. 1)      Required. The .dat file to import (overwrite an existing object). It is of the form `{asset display name}-{source file name}-{asset path id}.{file extension}` where currently only the path
                         id is used to identify the asset to patch.

Known Limitations

  • Currently only looks for replacing Meshes when using --by-name.
