Thank you!! I didn’t use any mGear facial rig solution as such. I found cable component very nice to achieve shapes based on a curve and tangents. In addition with the ik to another connected to anotehr part of the face rig.
I used it for lips, left and right, up and down, parenting the cable component under the mouth upper and bottom lip control, then set the ik to the mouth corner controls. Doing it this way the cable is constrained between the two of them and behaves nice. Then i did some custom rigging on top to control the tangent when manipulating the mouth corner and job done.
Pretty much the same for eyebrows: set them between frown and the side of the head.
I know is not very animation friendly, and pretty tricky with certain poses, especially lips…but I was pretty happy with the results, considering face rig is not particularly the strongest of my skills. 8-D
Learnt a lot out of it anyway, next one will be better!
