This goes to every single part in the Tori, as it's encoded that way:-
Each part has one object(.obj) and texture(.tga) assigned to it accordingly[.obj/_obj.tga], so if you have two objects activated the same time that occupy the same body part, it might choose one over the other or just completely fuck up the texturesrarely.
tl:dr - If the 3D item occupy same body part like head then no.
