Rig is distributed "as is".
It based on AdvancedSkeleton rigging system in Autodesk Maya app.
You can check out animation with Lou on vimeo channel https://vimeo.com/boristheartist
You can use it in any non-commercial projects. Feel free to modify rig, model and textures as you wish.

Tips and Tricks:
- FKHead_M holds additional face controllers attributes that are hidden by default
- Main root controller holds Bend controllers vis. attribute

Model was made by me
