Rigify pose Issue Mesh Deforming on knee 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.
Thanks for the support Candice babe. But I finally figured it out! Woo Hoo!

Alright so I figured out that my Z Axis in the legs were facing the wrong direction of the Original Human Meta Rig Armature.

So then I was like, That looks wrong. I fixed it but I still had an Issue.

But Then I finally figured out I had to fix the Z Axis of my Foot's Roll. Makes perfect Sense.

So all in all for those of you with this issue.
Look for your armature's Foot IK (Which should be that little bone sticking out from the back of your foot) Find that, click it and press N to open your Window.
Next! Scroll to the top in that window and find Roll.
Change the Z Roll till it's pointing Downwards/Backwards and Bam! You got it fixed.

Tip: Now if you want to make a Horseman Just make your Roll face towards the front or   The Opposite Direction.
