The controllers created when rigging spines may differ according to the way the character is designed and the available joints. All possible controllers are:

As usual, it’s much easier to animate the rotation of the available controllers (FK) than their position (IK), even if for beginners animating the position might seem more intuitive.


When rigging insects, it’s better to rig the abdomen as a tail, and use a simple spine rigging for just the thorax and the head; that makes more sense in terms of animation.
