Alright, so I probably wasn't cut out to be a rigger. Transforming the IK settings back to zero makes the foot react crazily later on so I'm back to square one.

My problem is circled below in red. The toe joint on the left has the red/blue/green line pointing in opposite direction to the toe joint on the right.

How do I change this!?!

It happens when I mirror the joint from the left leg (to the right of the pic) to the right leg, but I can't work out why.

All help welcome.

Thanks, the Yeti
