Cannot find the path to access texture field in MMD material

[ArpegorPSGH]

Hello,
I am trying to write a script to automatically create MMD materials inside Blender as copy of existing ones, but with the addition of a texture. However, I can't find a way to access the texture field of the MMD material to give it a value. How could I manage that?

Thank you in advance,

Here is the pseudo code:

from mmd_tools.core.material import FnMaterial

source = FnMaterial(source_material)
target = FnMaterial(target_material)

source_base_tex = source.get_texture()
if source_base_tex:
    target.create_texture(source_base_tex.image.filepath)

source_sphere_tex = source.get_sphere_texture()
if source_sphere_tex:
    target.create_sphere_texture(source_sphere_tex.image.filepath)
target_material.mmd_material.sphere_texture_type = source_material.mmd_material.sphere_texture_type

target_material.mmd_material.is_shared_toon_texture = source_material.mmd_material.is_shared_toon_texture
target_material.mmd_material.shared_toon_texture = source_material.mmd_material.shared_toon_texture
target_material.mmd_material.toon_texture = source_material.mmd_material.toon_texture

#Another way
copy_material = source_material.copy()

FnMaterial(copy_material).create_texture(filepath_of_base_texture)

FnMaterial(copy_material)..create_sphere_texture(filepath_of_sphere_texture)
copy_material.mmd_material.sphere_texture_type = "0", "1", "2", or "3"

copy_material.mmd_material.is_shared_toon_texture = True or False
copy_material.mmd_material.shared_toon_texture = 0 ~ 9
copy_material.mmd_material.toon_texture = filepath_of_custom_toon_texture
