AWESOME! I was playing around with this rig for a bit, and thought there was no IK for the arms, and was dissapointed... but I figured out the solution (didn't watch the tutorial videos, I have no idea if it's in there or no). So for anyone having trouble with this: just select a bone, and hit T, to open the toolbar (tool tab, whatever you want to call it) and scroll down, and set Arms IK from 0.00 to 1.00 on both arms! There ya go, both arms now have an IK control!
Again, AWESOME, great rig, and I will DEFINITELY use this in the future!
It sure takes a long time to render... On ALL of my computers... This isn't going to help my process of making things, like at all. I don't know what to do in my spare time. Plus somebody might close it on accident, and I'll have to restart the rendering all over again... The other rig model that I use, renders perfectly, but this takes like 2 ½ days. (sarcastic)
