Another classic animation rig. This one is great to work through early animation exercises, or to continue honing your craft. I've been using the rig in my classes for a few years now and the feedback has been great!
If you like the rig, feel free to tip me what it's worth to you, or send some positive thoughts my way ;)
[Last tweaked in Maya 2014, may work in earlier versions.]
Posing Tips: The spine is an FK setup that can be translated to push the pose. The mid back control has the Squash/Stretch attribute, and the base control has rock forward/backward sliders, as well as a few other useful settings.
