There are some things which V4 does well. The knee and elbow bending is greatly improved. Some things start well, but end badly. Look at the UV mapping of the limbs, all nicely aligned with the UV-map axes. Great, it makes a lot of shader tricks much easier. But one limb is at right angles to the others. Likewise, the boundaryu between face (on one texturemap) and back of the head (on another) passing in front of the ears. It's visible. And the texturing is essentially P4 fed through a few P5+ shader nodes. They've crippled themselves with DAZ Studio compatibility. Things like the shortage of morphs--no spandex morphs, for instance--and the shortage of clothing, can be improved over time. But the weaknesses I've described are rather more fundamental. And DAZ have never been good at documenting their models. So I took advantage of the opening offers, but I'm not using her, not yet.
