upackage is a python module for generating *.unitypackage from source assets without unity.
pip install upackageGiven the following setup:
some/path/to/my/content/
some/path/to/my/content/code.dll
some/path/to/my/content/object.prefab
some/path/to/my/content/code.dll.mbd
The command will generate a package that installs the content of "some/path/to/my/content/" into "Assets/content/". It uses the last folder name in the path as the containing folder for the assets.
UPackage.preprocess_assets("some/path/to/my/content")
UPackage.generate_package("some/path/to/my/content", "output.unitypackage")The tool also supports CLI access:
upackage some/path/to/my/content output.unitypackage*.meta files will be generated if they do not exist for files & folders.
