Good rigging Tutorials?

Hi, I’m pretty terrible at rigging and unless it is a simple automatic weights rig with auto IK, I don’t know how to do much else.
I was wondering whether there are any good tutorials that helped you out?
More specifically character rigging tutorials that include facial rigging?

Any replies would be greatly appreciated, as rigging is definitely something I have to work on.

Thanks

To the above excellent list, I would add the Character Animation Cookbook from Packt. You can pick it up few a few $ and it’s a solid resource. Half the book is pretty detailed rigging stuff.

I haven’t seen this… I might have to pic this book up and take a look… I"m always interested in more source matterial…

cgcookie has a very good video on basic riggin of a humanoid character

and then downloading and studying the constraints in these models would help you with rigging of “hard” objects like mechanical components
