Quote - My guess is that the labia are visible in those renders because the insides of the vulva are not mapped yet. Antonia's is by default almost flat in that region. There's a little dent, but that should not be visible with this kind of texture.

You're going to have to make a morph for that area, as that part I'm mapping separately from the SkinHip Mat zone of the Hip & Hip2 actors.  That area I'll be labeling SkinVagina, and mapping it to use my PosetteV3wG genital map (which of curse will be included in the package.  
But the truth is, if you're going to include a genital, then you need to include some morphs to make the genital work.  (And why not, it generally works on Real Humans, so why not digital ones?).
