A rig made it to practice body mechanics, is my first attemp doing rigging so I hope you like it. Download and comment to help me improve it.
Thanks for the rig. Unfortunately, everybody makes it, perhaps, too convenient for us, by creating a rig with IK spine. And that type of spine is problematic for body mechanics students. I have failed yet to find one rig, even the paid ones, that has a sophisticated 3-controller bones for the spine, except a free rig called Stretch by Tribee and Aeon Production, but that one too has some issues with the bend controllers (could be just me though) . So in all available Blender rigs I find one controller for the whole spine, and that messes up the spine overlap principle and makes your animation look clunky, or makes your workflow cumbersome at best. That is not to say that your rig isn't good, not at all, it's really awesome. It's just, along with many others, not catered for in depth body mechanics study.
