Error: Can not loadUE3 packages

[Sven-vh]

I created a basic blueprint in the latest Unreal version, version 5.4.1, but when I try to open it I get an error: An error occurred: Can not load UE3 packages.

uasset_path is the path to a .uasset file.

def get_asset_type(uasset_path):
    try:
        print(f"Reading uasset file: {uasset_path}")
        provider = DefaultFileProvider(os.path.dirname(uasset_path), VersionContainer(EUEVersion.LATEST))
        provider.initialize()

        uasset_stream = BinaryStream(uasset_path)

        package_reader = LegacyPackageReader(uasset_stream, None, provider=provider)
        package = package_reader.read_package()
        primary_export = package.exports[0]
        return primary_export.export_type
    except Exception as e:
        print(f"An error occurred: {e}")
        return None

UE5.4 is probably too new for pyue4parse and this package is not updated anymore. use this https://github.com/FabianFG/CUE4Parse

Thanks for the quick response, the problem with CUE4Parse is that it's for C#. I'm working in Python. The only thing I need to know is what type of asset it is, is there a workaround for this?

Is the asset you are trying to read cooked?

Sorry for the late reply but, No, they are not cooked. Does this make it easier?

Library is only tested with cooked assets
