I am doing my first Facial Rigging, and at the moment I have a specific question on rigging the lips:
Look at the image below, as you can see I am using cubes as lip bones. But you will also notice that the shape I obtained is too squarish, as opposed to being rounded. My intention was to put the lips as if he's whisling.
What does it take for a more rounded shape to form? More and smaller bones?

Thanks in advance guys :)

Dr,

How do you wanna control the lips? - do they need to go up/down/left /right? roll and twist?
Are you going to add a mesh smooth on the top? or is your skinning modifier over the top of a mesh smooth?

You could either have the bones/controls in a float list stack so to have them controlled with an expression/script - then on top an xyz for manual control. Or use weighted list controllers to blend stuff. - or even localized mesh smooth?

Hi Eek,

First off thank you kindly for replying :)
Well, I need them to do all the typical positions for lip-synch. So far I had thought I would do it with morphs, but now that I just read about the scripts way I am not sure anymore. But before I get that far, right now I am still defining the rigging. My concern is how to get the lips to do curvy shapes when my lip bones are cubes? I guess I have to blend the weights between the bones, right? So far they all have their vertices to 100%.

Thanks in advance Eek,

Right well firstly im guessing, your using max. And to blend the weight of vertex skinning - well thats gunna be tough. I looked into this and to firstly find the value and the vertex, let alone drive it somehow is gunna be difficult.

If you mean standalone skinnng, yes your right 50-50 is a good way to start. Basically weight the vertices to a bone at 100% then hold control and select your next bone then weight off the values 50%

Its a mixture of good weighting with these rigs and good control placement. Skinning comes with practice and time, rigging the same.

Also is each cube manual? or driven by something? a script an expression?
