Hi,
I have a quick question about a neck setup. I’ve been doing one extremely similar to jason schleifers AFR, but when I translate the head from side to side the whole head rotates from side to side also…
The ik spline goes on an arcing angle as opposed to a squiggly line that would cause the head to stay oriented upward.
Here’s a picture to demonstrate what happens, red line is how it should look… roughly. Anyone have any ideas how to fix it or what causes it?

They’re hidden in that image.
