How do I fix the this rig to blend it's knees the right way? i'am currently having a problem with my rig. It doesn't wanna seem to blend like a normal leg would. I noticed this problem after I added the Inverse Kinematics. Here are some pictures.
When you add an Inverse Kinematic constraint to a bone, the Inverse Kinematic panel, in the Bone tab, allows you to lock the axes you don't wont the bone to rotate on.
