More UV mapping issues, especially misalignment between the front and the back on the insides of the legs

[JupiterRowland]

If anyone feels like improving the UV mapping on Ruth2 v4, they may take a closer look at the seam between the front part and the rear part along the insides of the thighs and the crotch.

• Especially along the insides of the thighs, the UV mapping of the front part and that of the rear part are misaligned towards each other. This is combined with the UV mapping of the inside of the thighs on the front part being very distorted.
  Above ca. half the length of the thigh, the UV map is bunched vertically which causes the texture to be stretched vertically, the more, the closer it gets to the seam between the front part and the rear part. The rear part appears to be okay. For example, this causes the upper edges of thigh-high stockings to be "torn apart": It wraps around the front of the thigh rather straight. Then, on the inside, the closer it comes to the seam with the rear part, it curves upward, the more so, the higher up the leg it is. Right at the seam, it sharply drops to about the same level as on the front of the leg.
  Further up, the UV map is stretched vertically as if to make up for the bunching below and above. On the body, the texture is bunched together.
• In the crotch area, the UV map of the front part is bunched again, partially so extreme that single pixels are stretched to enormous sizes on the body. Underwear, swimwear and the like that passes through the crotch but shouldn't cover the leg bleeds onto the leg if it's wide enough.
  Meanwhile, the rear part in the very same place has a stretched UV map which causes whatever passes through the crotch to be as narrow as a shoestring.
• Also, in the crotch area, the UV map of the rear part seems to extend into areas of the texture which are not meant for UV-mapping, and which are not UV-mapped on the system body. I've come across pieces of layer clothing which have a huge gap in the crotch.
• Across the crotch, the seam between the front part and the rear part is not straight. Rather, it does a very noticeable curve towards the front which distorts crotch textures further.
