I'm currently working on a project, which involves a mechanical cat-like machine. Attached is a pictures of the spine and the bones that control it. Notice the sets of pistons that makes each verabrae move, this setup required a lot of wire parameters to get all the rotations to work correctly. In order for the pistons to work correctly, all the small bones (that control the linkages) are wire parametered to the Larger bone behind it, so that both angles on either side of a smaller bone are the same. This works really well, other than the fact that I can't really apply IK to it with predictable results, I want to use spline IK to make it easier to rig the rest of this quadruped. I have tried making a second bone structure and linking the first to that one, but it doesn't inherit the IK, also, is there a way I can constrain the rotation of the bones, so they can't rotate too far? I have tried to do this in the heirarchy tab, I can set it as active and the limits are correct, but the bones have no change, they seem to ignore it... anyway... any help would be appreciated...
