I have this problem with my leg rigging.
Every time I move it up with IK Leg it would bend the opposite direction which would make my character look like a Centaur. Cool but not what I'm aiming for.
Why does it do that but I think it could be because of how I created my character. I created him facing the back view. So when I added my Human meta rig, I rotated it 180 so it can face backwards. If that's the reason why can someone please tell me how I can fix that with out starting a new Human Meta Rig?
Here's what happened when I tried to fix it by placing the knee's target in the front instead of the back.
Here's how it looks when I don't fix it.
