If you don’t have Stephanie 5 this set won’t work. The texture obviously requires her UVs which are different enough from Vicky’s to bork things up when you apply it. Even though you don’t want her morph you’ll still need to buy her to get the correct UV mapping for that and any other Stephanie 5 skin.
Nice. I forgot what those morphs looked like, it’s been so long… though just for giggles I converter her to V5 to see what she looks like next to her old M4 counterpart.
