Hi! I’m making script-plugins in Python. Currently I’m trying to get objects, that camera sees through the frame range of camera cut section.

def find_rendered_objects(camera_cut_section, sequence, step=10):
    unreal.LevelSequenceEditorBlueprintLibrary.open_level_sequence(sequence)
    unreal.LevelSequenceEditorBlueprintLibrary.set_lock_camera_cut_to_viewport(True)

    start_frame = camera_cut_section.get_start_frame()
    end_frame = camera_cut_section.get_end_frame()

    bindings = sequence.get_spawnables()

    rendered_bindings = list()
    for frame in range(start_frame, end_frame, step):
        unreal.LevelSequenceEditorBlueprintLibrary.set_current_time(frame)
        unreal.LevelSequenceEditorBlueprintLibrary.refresh_current_level_sequence()

        for binding in bindings:
            binding_id = binding.get_binding_id()
            objects = unreal.LevelSequenceEditorBlueprintLibrary.get_bound_objects(binding_id)
            for obj in objects:
                if unreal.Actor.cast(obj).was_recently_rendered(0.0001):
                    rendered_bindings.append(binding)
                    bindings.remove(binding)

    return rendered_bindings

The problem is, that the execution blocks the render during run and the functions was_recently_rendered() doesn’t work properly. Is there any method in Python Unreal API, that can force update/refresh viewport?
