@Alan Strange Leg IK Handle

Hi Alan, I'm trying to finish off the maya character tutorials with all the rigging parts but when I try and create an IK handle from the hip joint to the ankle joint like in the tutorial something strange happens which results in the knee joint snapping back to be in line with the hip and ankle joints. I've never had this happen before so I'm really not sure what's happened there.

Leg joints fine before trying to add IK handle.

Result from adding IK handle.



Is this a problem and if so do you have any ideas on how to fix it?

Thanks!
Emma
