I just wanted to share this link to my maya facerigging tutorial video series.
I have been working at MPC, Double Negative and ILM, and I thought I would make a tutorial series on how I go about rigging my own characters.
See the tutorial page here:
It's a tutorial series that will take you though how to set up a facerig in Autodesk Maya from start to finish and all you need to know is basic Maya navigation.
At the end you should know how to create facerigs in Maya ready for Animation of dialogue and song.
