Spline IK setup for spine, lots of joints driven by one long spline with a few handles.

There's a 'Bendy IK' that I would like to learn how to use in future that incorporates both spline and regular IK that the maxon tutorial teaches but it looks far too complex for what I need so I use spline IK also for the arms here which need to be more flexible than regular elbow joints like the the other characters as they are so long.

Regular IK leg chains and spline IK arms are set in the spine heirarchy so controllers affect correct areas.

Once again, the bendy shape weighting took a very long time to get smooth when the controllers were moved around. The smooth tool within the weight tool had to be painted around the whole body for each joint to ensure it doesn't crease or pinch in places.
