You can tweak a bit the script to:

  • make it iterate on actors in your scene
  • for each actor you will select them
  • then export to gltf but only the selected elements

In the following code notice that:

  • task.object is using the world
  • task.selected is true (if you do not it will export the full level)
  • task.options is a unreal.GLTFExportOptions()

You can iterate over actors and select them with something like that

for actor in unreal.EditorLevelLibrary.get_all_level_actors():
    selected_actors = [actor]
    unreal.EditorLevelLibrary.set_selected_level_actors(selected_actors)

and then you can export each selected actor or group of selected actors.

    task = unreal.AssetExportTask()
    # this could be just one asset if you only want to export one single asset
    task.object = selected_actors[0].get_world()
    task.filename = output_file
    task.selected = True
    task.prompt = False
    task.automated = True
    task.options = unreal.GLTFExportOptions()
    unreal.Exporter.run_asset_export_task(task)
