Week 3
This week, we begin weight painting the model. Starting with the mouth, as this would be the most difficult and was the area with the most joints, as well as the most crucial part of the face to express emotion.
I started by binding the joints to the skin, and then rotated the jaw open slightly to see what I would need to remove influence to and add influence to other joints.
Once I had rotated, I was greeted with this monstrosity of nightmare fuel. To fix this, I began going over all the polys that were stuck to the top of the mouth, maxing the influence set by the Front Jaw joint.
After doing this for about an hour or so, I had made it look far more presentable. I could then go about weight painting the influence of the lip joints. I opted not to add tongue joints as this would make the rig more complicated than I would have liked. (And I'm not the most comfortable with weight painting.)
I went around the joints of the mouth, painting very similar influences, heavier closer to the joint with a blend of lower influence on the outside. I also did this with the jaw influence, as you can see in the screenshot above this one.
