I have a leg with a foot at the end. On each step, I want to pull the foot into the leg, because the feet are like piston points.
When I do this, I want the IK to move down an equivalent amount so that he foot doesn't actually come "off" the ground.
To do this I set up a transform constraint between the foot and the IK node at -100 transform, so the IK node does the exact opposite of what the foot does.
This works.. until you move the hips that the legs are attached to, which causes the feet to rise up off the ground. Everything I've tried to do hasnt been able to solve this problem.
If I set the foot -> IK constraint to Local or Relative, it stops doing 1:-1 movement with the foot.
Is this solveable?
