Hello everyone...I've begun a series of tutorials for facial expression and viseme rigging using the Makehuman Alpha 8 mesh and Blender 2.69.
You can access it here: http://geekopolis.ca/wp/?page_id=39
and here: http://geekopolis.ca/wp/?page_id=78
The full viseme set can be found here: http://geekopolis.ca/wp/?page_id=102
The model is free to use, and updated daily. It will contain a full set of visemes, facial expressions (+ blink), and walk cycle.
