ERC (also known as JCM and many other initials) is simply a way to
link the movements of one joint or morph to another. It's used in
most of the major figures, often to control breast morphs from collar
or shoulder movements....
When a paragraph like the one I've shown is added to a parameter,
it will move whenever its 'master' moves. The master figure is the
second line (usually Figure 1 will do, but you could also put the figure's
proper name if it has one). The master body part (here the head) is
the third line, and the master parameter (here OpenLips)
is the fourth.
The last line gives the 'control ratio'. I picked 8 by observing that the
widest usable opening on this figure was about OpenLips = 1.8,
and the teeth seemed to match when their xRotate was about 14.
Slave move / Master move = Control ratio.
so 14 / 1.8 = 8
