Comparing Genesis 8.1 Female, Victoria 8.1, Genesis 9 Female and Victoria 9
Comparison 1
Genesis 8.1 Female , Victoria 8.1, Genesis 9 Gemale and Victoria 9 out of the box.
Genesis 81.1 Female and Victoria 8.1 use the Victoria 8.1 skin, which is the same as the Genesis 9 Feminine Skin 01 (even the picture is from Victoria 8.1). This skin is also used for Victoria 9, all have the same skin.
All also wear the Cruise Bikini in white and Voss Hair.
Arms are posed down at 100 %, and legs for Genesis 8.1 and Victoria 8.1 spread at - 8.1 %, i.e. poses are the same as well.
First thing I noticed is that Genesis 9 is small. Victoria 8.1's height is listed as 5' 8" (172.8 cm) which is a good average of a Western European woman.
Genesis 9 is smaller, even the male base. This is wrong in my understanding. I would have expected the unisex base to be as tall as Genesis 8.1 female, and then becoming smaller for women and taller for men.
Comparison 2
Genesis 8.1 Female, Victoria 8.1, Genesis 9 Female and Victoria 9 as in comparison 1, but adjusted to the same height (Victoria 8.1's).
What seems to be wrong is that Genesis 9 Female and Victoria 9 have longer arms. I never heard complaints that Genesis 8.1's or Victoria 8.1's arms are too short.
Also, without HD morphs on any of the characters, the body details of Genesis 8.1 Female and Victoria 8.1 Female are more detailed.
The shoulders of Genesis 9 Female and Victoria 9 Female look to strong, i.e. square, but that is my personal taste.
Comparison 3
For a back to back comparison I have switched the positions of Victoria 8.1 and Genesis 9 Female.
Genesis 8.1 Female and Victoria 8.1 have more of hollow back posture.
The arms of Genesis 9 Female and Victoria 9 are stronger, which is probably more realistic.
The breasts of Genesis 9 Female and Victoria 9 are set a bit lower . And more saggy, probably due to the unisex base.
Comments
There's a thing I call the Di Vici test, the distance from finger tip to finger tip should be the same as the distance from the top of the head to the bottom of the feet.
The big problem I always had with pre-G9 was trying to get proportions to be physically correct. First and foremost the eye size (eyeballs) were grossly out of wack (something like 50% larger in diameter, making their volume 3.3x what they ought to be), and trying to get them to scale down to an anatomically correct size (~2.4cm +/- 0.1) involved having to export into Maya and pretty much resculpt the whole head. The fact that G9 seems to address this, along with more robust shoulder girdle behavior is very welcome. I still think the rigging in the clavical area could use some work, as it seems to flex/bend rather than rigidly pivot near the sternum. Elements relating to basic height, musculature, soft-body sag are really trivial things that can be addressed through tweaking a few morph sliders.
yup i made an eyeball scale morph that didnt really work because it made the back part of the sclera apparent, which was usually painted dark so I had to lighten those parts. Then I resized it in a way that kept the back parts in the back but that caused texture stretching.
the g8 shoulders looked really wonky in animations like not well-defined enough, maybe that was fixed in g9
A base model cannot have features that are too strong, or it will make it hard to change the look of a character - anyone remember the first Michael morphs? It took an extreme effort to make the face look like anything other than Michael (and based on Dan Far for that model which I always found amusing).
A base model has to cover all sizes, not just one particular group... in some countries 5 foot is the average height, and that is my height too. Scaling a 6 foot amazon down never looks right, the hands and head proportions are wrong. With the proportion dials on G9 you can now have a 6 foot V9, but ALSO a 5 foot tall V9 - and the proportions will still be correct.
There's a lot of breast morphs in the shapes pack, so not too hard to move the breasts around to the shape you prefer.
My 2 cents :)
Yeah doing any sort of scaling with the eye geo requires you to make sure you maintain the same distance (not ratio) between the layers of the eye, otherwise you risk z-fighting or intersections on account of the already-small gap getting too small.
5'8" for a woman is quite tall. In the US, the average woman's height is 5'4".
I'm glad they finally scaled down from the nearly 6' females, you had to scale them way back to get anywhere close to average. Then of course any poses included with props are quite off when you scale them to a more reasonable height.
I am very pleased with the shape of G9/V9, I find it more realistic than G8/G8.1 :)
