System: Windows 10
iClone: 7.83

Please look at https://wiki.reallusion.com/IC_Python_API:RLPy_RIMaterialComponent#LoadImageToTexture_.28_self.2C_strMeshName.2C_strMaterialName.2C_eChannel.2C_strImagePath_.29

I am trying to change the Diffuse or Base image in iClone via python script but RLPy.RStatus.Success is always 0 and the file is not uploaded.

The character I am using is the default one in CC3 I just used the transfer to iClone button.

Attached is the image I am uploading and the script I am using.
Any help is appreciated. Thanks

My script

import RLPy

avatar_list = RLPy.RScene.GetAvatars()
avatar = avatar_list[0]
material_component = avatar.GetMaterialComponent()

result = material_component.LoadImageToTexture("CC_Base_Body", "Std_Skin_Head", 6, "D://test.png")
print(result.Success)
