I've setup an IK rig that uses an IK pole to aim the knees, and I'm wondering what is the best way to have these IK poles follow the rig? Ideally, the pole would always be directly relative to the knee it controls, like a planet orbiting the sun. But I can't seem to parent it to the leg without causing strange issues (because the leg is changing relative to the pole and the pole relative to the leg).
Any ideas on how I can accomplish this without the feedback loop issue?
Another secondary question related to IK - how do you toggle IK on and off during animation? I thought about using a driver linked to the influence factor that could be rigged to some type of user control, but it seems like it should be easier than this?
