I want to assign different material instance for each StaticMeshComponent. First, set material for StaticMeshComponent, then set material.  
I’ve tried different ways, set `override_materials` property, or `set_material(0, material)`. Nothing happened. Also, `get_material_slot_names` returns `[]`, `get_num_materials` returns `0`. but there are two material slots in the mesh asset.

```auto
children_components = root_component.get_children_components(False)
    for child_component in children_components:
        if not isinstance(child_component, unreal.StaticMeshComponent):
            continue
        components.append(child_component)
        child_component.set_editor_property('static_mesh', mesh_asset)
        print(child_component.get_material_slot_names())
        print(child_component.get_num_materials())
        child_component.set_editor_property('override_materials', [material_example, material_example])

```
