I am currently trying to automate different redundant actions i have to do with unreal with the python api. And i am having some difficulties on accessing the static meshes components that are inside my loaded blueprints through python… Has someone ever managed to achieve this ? Because I can’t find any function in the BlueprintEditorLibrary nor in the Blueprint class that allows me to access the child components of my loaded blueprint 
If they’re actor blueprints have you tried calling “get_all_child_actors()” on the blueprint and then looking for meshes in the resulting list?
thx for the answeer !! however i tried using it and i get an error :
AttributeError: 'Blueprint' object has no attribute 'get_all_child_actors'
and I am calling this function after loading the asset and calling unreal.BlueprintEditorLibrary.get_blueprint_asset(actor)
