In the movie industry, and gaming, an efficient way to retain volume and deal with artifacts with extreme bending of joints, is by using 'Corrective Blendshapes'. This is done using Maya, Max, Blender, Houdini and C4D, among others. it was recently showcased to be used in the game God of War. Like mentioned in the forums, this tech has been around for years, but with Poser its still a big problem. Evolution, as well as some other Poser figures, and DAZ's Genesis, make a lot of use of such 'Blendshapes'. Comparatively, although the weight maps do a lot of the bending firstly, Evolution makes very heavy use of these blendshapes, especially since it is an art figure that is focused on achieving realistic bending every step of the way, every angle and direction (and also avoiding some bulging errors that occurred with scaling, fixed in P11 I believe). Much more improvement can be done, but the focus on blendshapes was a very deliberate design choice inspired by the very same thing that originally inspire Larry Weinberg to make Poser in the first place: to use as an alternative resource for drawing human models. Humans are very dynamic, squishy things. They squish in all directions, and they squish even more differently at extreme angles. I intentionally put them in Evolution because of this, but they are very hard to transfer to clothing. If an artist with a $1 pencil can draw in these curves, how can a $500 CGI package have such trouble with this? In Poser these 'Corrective Blendshapes' are called 'Joint Correcting Morphs' (JCM) and they seem to have a very bad name.
