Hear hear on the use limits!!! I've gotten freebie packs with better attention to the limits (which WORK! darn it) than the ones I've paid for! And I'm not talking just IK, either -- I'm talking simply working within the limits that were defined for the joint -- it's a double click on the dial away to see what they are (even easier in P5), it's in the manual, but it's ignored becuase it's easier to do it the other way -- spin until it's close. While not all of the "bent mesh" issues with close joints like elbows and such can be fixed with this, one hell of a lot of them sure can be...

thou and I, my friend, can, in the most flunkey world, make, each of us, one non-flunkey, one hero, if we like: that will be two heroes to begin with. (Carlyle)
