How to add Actors to Map in MoviePipelineExecutor before rendering

Development Programming & Scripting

Hi. I’m new to UE, and I’m working with python script about MoviePipelineExecutor.

Up to now, I code my own MyExecutor(inherited from unreal.MoviePipelinePythonHostExecutor), and successfully run from Command-Line.

But, I want to add some Actors(such as a Cube or a Camera) to my map before render it. How am I supposed to do since I have the same issue posted below:
Unable to use EditorLevelLibrary while creating a custom Movie Pipeline Executor in python

Am I wrong about this idea? It could be logical if editor-opertations are required to be done before MoviePipelineExecutor. But if so, what does on_map_load work for?

Thank you for any reply.
