Rigging a hunched spine

Rigging
1

I was wondering how people here approach spines that curve over or hunch. A straight spine won’t get good deformations, but curving the spine provides strange rotations of the torso to coincide with the joints’ orientation.

pics related - having a straight spine wouldn’t deform well, but the curved spine obviously affects how certain parts of the mesh rotate with it




Any insight would be greatly appreciated :slight_smile:

Controls don’t have to be curved, rotation of spine control vs. local twist down the spine can be decoupled, you can flatten it out a little bit and move it slightly backward and throw a helper joint, or two in front of it to help with “abs” volume.
