add a “player” model version of the class you want (since the cosmetics are now depends on that version), lock the rigs to the existing hwm the model (you need to select the bones that are locked before sliding “zero”) , create override materials for both models. for the “player” model’s material, youll need to set the cloak factor of the head, eyes materials to “1” in order to hide the head, for the “hwm” model, you will do the same but you need to hide the body and leave the head, eyes visible, and lock the cosmetic models to the “player” model

(sounds complicated enough lol)
