You might take a look at this approach:

Also, "The Art of 3D Toons" from CGToolkit has a non-blendshape/non-bones approach to facial animation:

1-how to prevent lips passing through each other?

You could do this by creating a blendshape that triggers when mouth closes or use other deformers such as lattice and sculpt deformer to push the lip from passing through...

2-how to add local tweak to character which combines corretly with blendshapes?(i actionaly found the answer but lookin for a better one.)

You can create some deformation facial rig which consists of Delgo like features with wires and controllers. The deformation rig can be then used as a blendshape to layer on top of the bound, original facial setup with other blendshapes aand controls...

thanks Boucha.would you make it a bit more clear for me?did you setup something similar using this technique?

You could do this by creating a blendshape that triggers when mouth closes or use other deformers such as lattice and sculpt deformer to push the lip from passing through...


you know, i think this blend shape target couldent be somthin static.maybe i should create
a copy of face in wich the under lip follows the upper lip .and to make underlip open/close i should change that targets weight value.

What I mean to say is that you create a simple blend shape ( corrective shape ) for e.g. lower lip pushing upper lip ( more like what we can see in front of a mirror, you can try that..). You, can then create a set driven key relationship between the jaw joint rotation ( for example ) and the blend shapes weight value...You can try the same with lattice by creating clusters on lattice point ( for lower and upper lip ) and do a simple set driven key on the transformation of those cluster in relation with jaw joint's rotation...

thanks for reply Boucha.but what i mean is more than that .i want the mouth to be closed as i push the close value to 1.even if other mouth blends aren't 0.i.e. i make the character laugh and even now as i make close value 1,the mouth is shut correctly.
