I have been trying to rig a quadraped (cat) and I have lots of issues that have me puzzled as to what makes a good rig. The biggest issue, right now, is how to incorporate the shoulders and spine into the rig. It was easy to rig a biped, but the four legged character seems to present more issues, like how the shoulders and spine interact with the hips. It is kind of like you want to have two parents of the spine. In motion, the hips drive the shoulders, but the shoulders are able to move independently from the hips, like when the animal is changing direction.
I have looked for reference for rigging quadrapeds, but there is very little out there. And what I have found has not been too great. Anyone have any suggestions, ideas or tips? Thanks.
