I have a model about blender,there is a object （name's car_AudiA8） with multi-material，I want to copy a new object from the object ("car_AudiA8"),then change new object's color and old object's color is not affected,my method is :

obj = bpy.data.objects["car_AudiA8"] mesh = obj.data new_obj = bpy.data.objects.new("car_AudiA8", mesh) bpy.context.scene.objects.link(new_obj) bpy.ops.object.make_single_user(object = True, obdata = True, material=True,texture = True ) for slot in bpy.data.objects[new_obj.name].material_slots: if (slot.name.startswith("carpaint.Black")): bpy.data.materials[slot.name].diffuse_color = (1,0,0)

but when the method doesn't work,I don't know reason. when render the object , car's color doesn't change.

Script works fine, but maybe you use cycles? – Crantisz Jul 03 '17 at 08:01

I render model with python . I use the code --"bpy.ops.render.render(write_still = True ) " – user824624 Jul 03 '17 at 08:50
Ok, you have cycles renderer, but diffuse_color is internal renderer value. So you mast recreate you materials to internal, or change color in nodes – Crantisz Jul 03 '17 at 08:57
