Okay; so I couldn't resist and bought the V4 pro kit (yeah, I'm stupid like that) and the basic clothing set, and I thought I would give anyone who wants to know my initial impressions of V4 after playing around with her for a few minutes:

1. This figure is VERY different from all the other unimesh figures; her part grouping and morph grouping is much more like the e-f figures; I liked the fact that the morphs are grouped by body part, this makes finding individual morphs much easier. She actually seems to be a little taller then V3.

2. V4 is NOT compatible with V3 clothing, textures or morphs. The V4 to V3 figure (note: this does not seem to be a part of the "base" package, it only comes with the morphs) cannot take V3 morphs at all from what I can tell...not much use.

3. Joint bending seems to be better....her elbows could still use some work, but the hip and shoulder bends are better when compared to V3...she doesn't have (as bad) a creasing problem, but it still could be better.

4. This is a just personal opinion, but I think her head looks a  little too large for her body....her overall body shape seems "younger" than V3....she looks more like a teenager to me. I'm not really wild about her hip shape either...again, too much like a teenage model's than a real woman's, but nothing the right morph combination probably can't fix.

5. V4's breasts are more realistic looking than  V3's, with some better shape and movement morphs (I never did like the "breast 1, 2, 3" stuff  for V3). Oddly, the nipples are not "on" by default.

6. Her expressions seem to be MUCH better, much more realistic. She has some expression dials that will move her whole face for much more natural looking expressions.

7. Clothing fits are...interesting. Daz includes some "magnet' poses to fit clothing (but these are not actual magnets) by using crosstalk to morph clothing in sync with the figure. These don't seem to work with predefined character injections.

Overall; V4 is an intriguing figure, but not a must have right now. The almost complete lack of compatibility with V3 severely limits the appeal to me, as she is going to require all new content and textures, at least until there is a WW plug-in for her (and even then). I guess time will tell what kind of support she'll get from the community...right now, there is no matching the overall flexibility and support of V3, and I don't see V4 getting to that level anytime soon.

Thoughts? Other impressions? Questions? Feel free to respond.
