There are so many errors on V3/V4 (and prolly the other figures too) that it would make more sense to start building a figure from scrap than to fix them.
For your information, according to DAZ, V4 was build from scrap, that's why she isn't compatible with the unimesh figures. Problem with DAZ is lack of innovation.... they build a figure from scrap and arrive at the what they've created before.

*The problem is that DAZ now rather wants to make as much money as possible, instead of making the best product possible.
*It sure show lately doesn't it? Higher prices, lower quality. Misleading advetisments, promo images and promotion texts. But there seems to be a different change at DAz also.... while other stores are full of new releases, we see a drop in new items at DAZ. We see sale after sale at DAZ of old products, Bryce is on sale about every other week now, but hardly any new releases and most of the items released aren't worth the price at all. It also seems that many merchants (and users) are still very hesitant to create items for V4 or buy V4.

*V4 has no problems whatsoever in looking realistic -- or at least as realistic-looking as Poser figures get.  Even with clothes on her.
*I wouldn't call that V4 in that image realistic at all, she looks more like a stiff dressing doll you see in store windows, who can't express herself. She looks very unnatural and for sure not realistic in the image.

Artwork and 3DToons items, create the perfect place for you toon and other figures!
