That is because that’s an older mod that uses a different section for the nipple texture than newer mods.
The old nipple texture, however, also causes these ‘nipple slips’ which I’m not a fan of so I decided not to include these in the BP skins. The honoka body model never received higher resolution nipple textures and still suffer from this issue!
I made an updated version of that mod which should solve the problem SSR_Event_Tower (Nyo).zip
