22. There are several problems with the vertex influences for the head. First,
the head is a solid object and does not distort the same way that the torso
might. The vertices of the head should be locked to the head. Second, the
vertices that are influenced by the head in the shoulder area will cause those
vertices to shift position when the head moves. This will cause problems
during animation. The influences in these areas need to be removed. Go
back to Select and select the vertices of the head above the neck, as shown
in Figure 7.52.

23. Click on Assign to Link. Notice that when you select this button, the colored
plus symbols under Vertex Type change. The blue and green are deselected,
but the red remains selected. These buttons control how a vertex is bound
to the skeleton. Red vertices are those that can share influences with more
than one link. Green vertices are those that are bound to a single link,
also known as
rigid binding
. Blue vertices are those that are outside of the
influences of any link and are bound to the root node. Change the vertex
binding to green, as shown in Figure 7.53.
