Trimmed Image as Texture/Material

I looked a bit to the file, I quite understand but not fully.
When I bake the model object image is moving, it means that meanwhile a position and size of the texture was set, moving the object make them move !!! I don’t know if it is a feature or a bug ! @BrianJ have you some idea how to fix some texture coordinate on object in RH9 ?
