Weird Bone rotation

Hi,
This is my first character animation and I’ve got this problem with IK at the legs. If I move the foot IK just a little the knee bends fine. But if I move it more to the front the knee bends backwards all of a sudden.
Why is this happening and how can I fix it?

Look in the Animation workshop, There is a good way to overcome this problem, look under ik constraint. The trick is to use and other ik solver in the middle of the chain to pull the knee to the front.

hmmmm… well, if you want to see my way of fixing that, then just PM me with your email address… then I’ll send you a blend file which would hopefully help you a lot. :slight_smile:
