Hi there, I have a fully rigged and animated quadrupedal character. Leg IK is working wonderfully for the limbs! Trouble is I'd like to add an IK system on the spine that works in the opposite direction of the bones. None of the IK scripts appear to support this configuration, and give me this error: "Invalid/incomplete setup, can not initiate the solver. Invalid bone hierarchy detected. IK requires for it's bones to be parented to each other in descending order." Is there any way around this other than rerigging and reanimating the character?
