I'm looking for any good tutorials specifically about shoulder rigging. I've seen the Andrew Silke and David Clayton one on Cane Toad, and I've looked through the tutorials thread.

I'd like to know how to automatically raise the clavical joint when the upper arm rotates above a certain angle.

Any peoples could help me out?

are you opposed to expressions?

could just put a conditional expression in. something like

if (upperarmjoint.rz > 45)
claviclejoint.rz = (upperarmjoint.rz - 45) / 5;
else
clavicaljoint.rz = 0

another way,

claviclejoint.rz = (upperarmjoint.rz > 45) * ((upperarmjoint.rz - 45) / 5);

thats off the top of my head.

hope it helps.

Also look into set driven keyes. That is a really easy way to go. just raise the arm as teh driver, and then the clavicle can go up as the driven.
