Spine bending problems

I’m trying to improve the spine of my armature. Right now I’m concerned that when the spine bends the front of the torso stretches too much. The spine itself used multiple copy rotation constraints that each copy the rotation of the bone named Spine Base to an extent. The rotation Influence values are as follows:

Spine 1: 0.8
Spine 2: 0.6
Spine 3: 0.4
Spine 4: 0.3
Spine 5: 0.2
Spine 6: 0.1

What’s your advice?


I think it looks fine. If you’re worried, just set the rotation property of the bones as an IPO driver for a shape key that fix’s the deformation.
