I was looking at the 'body_torso.vtf' and 'body_torso_bas.vtf' textures for Curvy Elizabeth Daz5, and I noticed there's a, uh...phallic looking texture located up in the upper-left for both. Were there originally plans for the model to have a futanari bodygroup? I don't recall ever seeing an option for it when using the model.
It's for compatibility with the DazV5 futanari prop. https://lordaardvark.com/html/assets.html?cat=Models§=Props&asset=DazV5_Futanari_Attachment
