added updated version of my facial setup..

Basically, ive been trying to do facial setups for a long time. Bones, morphs etc dont really give me the freedom i want, and can also lose volume in the face. So i built my own setup, based on the muscles of the face. Ive got 14 controls in the face which give me about 196 combinations. And 8 controls in the eyebrows about 64 variations. The cool thing about it you can give nuance like talking out the corner of your mouth. Ill post some pics, and and version soon if anyones intrested.

Io,

This is the same problem im having. My system basically has vertices linked X form (clustered) onto paths, which bezier points are also constrained positionally between nulls. What you want is to put your clusters in a state of expression, moved into one. You dont want them locked into an expression because you wont be able to tweek them.

You need to design a neutral state, so every clusters trans/rot is zero'd out. Then to make expressions. Drag the poisition data onto the shelf as mel so you click the mel. And it goes into the Expression. Theres still serious problems with this:

Knowing where the clusters are in world space!(kind of makes it explode!)
Also no blending ability!

Most of my clusters are on paths which means when i record ther e positions for shelf macroscripts(MEL) it only records the pecentage, it doesnt rely on positional data.

but i still have the problem of blending. Also you may need addative effects to have i.e. make an oh -> oooh

Problems......... i'll have a think!

Eek

Eek, thanks for the file. I learned a few things that I otherwise probably never would have bothered with.

Thankyou..

Thanks..

I just love to animate, and setup up good rigs that work really well! for animators, ive seen so much bad stuff out there. Facial stuff is something ive been looking into for ages! And needed to design a system thats gives every possible gesture or emotion-its getting there! (Pixar is king for this kind of stuff, and this is where i got my idea. Basically they have multiple groups of vertices, using Gepetto software and then give them Avars animated varibles,and also i think they work across muscles lines.)

My system has four main mouth controls, mouth edges and cheeks. And ten lip controls.Pulling the edges cheeks affects the whole mouth, pulling and puckering,and then tweek the lips!!!

But anyway thanks again, and if anyone not only on this thread needs some help with rigs (Bipeds, Quadrapeds, anyped)- im always here (check it everyday).

More will come-
Maya 4, XSI version soon hopefully, goto add sliders as well!!

Eek

Update!

Beta version getting there!

Added sliders to control individual muscles. Still control corners of mouth and cheeks with points. Added Eye controller, no pupil dilation yet. Also need to setup whole expressions on sliders some how?

Select the slider point,then modify panel to use sliders.

Heres the file:
