So this is what has been keeping me busy these past few days.. I've found that a lot of rigs out there have hands where the knuckles would round out and look like pipes when they would bend.. They fingers would loose their volume and disregard the bone structure beneath the skin. Here's jackals hand system. The deformations took about a day to do.. There are a couple more things to do and iAnimate is starting soon... I've got to get this done and start planning on what I want to animate for workshop 5.
