Spine IK / FK (Toon Style) in Blender
This one, is based on my previous studies, I’ve set a chain of Bones for a Spine, with stretch/Squash functions, in IK. Also, theres two bones to control the top and bottom bones, in FK.
Also, you can work with the hips independently, keeping the top hyerarquie bones in the same or previous Position. This is interesting because sometimes in extreme situations, and not only, you need to reposition some bones while moving Hips or whatever bones - Its hard to do it.
