I know this is a long shot because the source has been hidden away in some corporate Electronic Arts server... but does anyone have an idea of how Maxis Studios accomplished their automatic weight-painting, rigging, and IK system for in-game character creation? Any scrap of information is good.
It seems that after EA bought Spore, they buried this technology with the death of the game. For reasons I don't understand, no other game to date has a character creation system like spore -- where the legs, arms, and body move differently depending on their custom shape. How did they do this?
