Kelley, IK can be removed, but its a manual process. You have to go into each bone and remove the IK modifier from that bone. Remove all the modifiers from the bones, and delete the IK targets and start fresh. Now repeat my process. Don't do the knee IK target though. Just go toe to ankle, and ankle to hip. And before you move anything set up your constraints. For your model, I'd say an axis constraint on the hip joint would be better then the ball joint, also use axis constraints on the knees, and a modified ball joint for the ankles and toes. The default constraints are not good enough, and require modifications depending upon what you are rigging. After you have it setup, move the targets slowly and carefully to make sure things(constraints) are setup properly. What happened to the eyeballs? Did this happen when the model was skinned? It could be a weighting issue. I need to write up a tutorial on skinning. There is a good tutorial in one of the issues of 3dxtract that someone did rigging a dinosaur. Brian
