Reimport Static Mesh using Python API

[ggHayda1 (ggHayda)]

Hi,
I am looking for a Python script that reimports the selected static mesh with the new file
I looked at the documentation for the Python API and could not find the needed functionality.
I want the script to do the same actions as if you pressed “Reimport With New File”.

This worked for me. If you want to reimport from the different path, then change “filename” in the asset_import_data

import unreal

def reimport_static_mesh(asset_path):
    """
    Reimports a static mesh asset in Unreal Engine.
    
    Args:
        asset_path (str): The path to the static mesh asset in the content browser
                         (e.g. '/Game/Meshes/MyMesh')
    
    Returns:
        bool: True if the reimport was successful, False otherwise
    """
    # Load the static mesh asset
    static_mesh = unreal.EditorAssetLibrary.load_asset(asset_path)
    
    if not static_mesh:
        print(f"Error: Could not find static mesh at {asset_path}")
        return False
    
    # Verify that the asset is a static mesh
    if not static_mesh.is_a(unreal.StaticMesh):
        print(f"Error: Asset at {asset_path} is not a static mesh")
        return False
    
    # Get the asset import data
    asset_import_data = static_mesh.get_editor_property('asset_import_data')
    
    if not asset_import_data:
        print(f"Error: No import data found for {asset_path}")
        return False
    
    # Create a reimport context
    reimport_context = unreal.AssetImportTask()
    reimport_context.set_editor_property('filename', asset_import_data.get_first_filename())
    reimport_context.set_editor_property('destination_path', unreal.Paths.get_path(asset_path))
    reimport_context.set_editor_property('destination_name', unreal.Paths.get_base_filename(asset_path))
    reimport_context.set_editor_property('replace_existing', True)
    reimport_context.set_editor_property('automated', True)
    
    # Perform the reimport
    unreal.AssetToolsHelpers.get_asset_tools().import_asset_tasks([reimport_context])
    
    print(f"Successfully reimported {asset_path}")
    return True

# Example usage
# reimport_static_mesh('/Game/Meshes/MyStaticMesh')
