I finally found something Poser 6 is good at. The Jessi character, out of the box, looks like something envisaged by the Brothers Grimm. With the head morphs from RDNA, she can be immeasurably improved. The supplied hairstyles can look reasonably good, provided the figure can be rendered at some decent level (or rendered at all - far from a certainty at Poser 6). I certainly shan't be abandoning all that V3 material any time soon. There are zillions of tons of material for V3 and very little for Jessi. Until the Poser 6 render engine works regularly, too, I shan't be dreaming of switching to Poser 6 permanently.
