export animation sequence from metahuman performance

Hello, I’m trying to create an animation sequence from a metahuman performance and the following code work.

import unreal

metahuman_performance_path = "/Game/.../NewMetaHumanPerformance"
metahuman_performance = unreal.EditorAssetLibrary.load_asset(metahuman_performance_path)

export_range = unreal.PerformanceExportRange.WHOLE_SEQUENCE

if metahuman_performance:
    try:
        metahuman_performance.export_animation(export_range)
        unreal.log("Animation export initiated.")
    except Exception as e:
        unreal.log_error(f"Failed to export animation: {str(e)}")
else:
    unreal.log_error("Failed to load MetaHumanPerformance asset.")   

The only issue I have is that it creates the “save animation sequence as” window and after pressing save the “export animation sequence settings” window pops.

This has been a normal behavior so far if I click on the save and create I have the correct animation in the animation sequence.

Is there a way to create the animation sequence with the options needed without activating the UI? My goal is to run this automatically using a batch.

Thanks in advance for the help.

Have you found any solution? I have the same issue and cannot automate this Process and Export Animation processes. I am not willing to use C++, but as long I can see so far, that is the only solution for this situation. Could you please let me know if you have found any other workaround?
