For those who would be interested, here is the Norman rig I am using.
The spine is in FK but as you will see, the spine controls are aligned to the world rather than their parent. This means that rotating the hips wont affect the rotation of the upper body. This seems a bit strange at first but this is proving really useful for walk cycles for examples as you dont need to counteranimate the upper body even after modifying the hips.
The file should open in Maya 2009 and up but also in older version provided you change the header.
One more thing you will notice is that the spine controls are transparent geometries instead of regular nurbs control. This makes the rig much cleaner and more user friendly.
It appears that I forgot to mention the constant use of a Xray hotkey with that kind of setup. Personally I use Alt+x to trigger Michael Comet’s Xray script (source “toggleXRay.mel”; toggleXRay();)
So you want to be a rigger huh?
