Re: rigging dilemma: driving a parent with attributes of the child

[David Gallagher <daveg(at)blueskystudios.com>]

Cool. Thanks Brad. It's not a solution for this, but there are lots of 
goodies in the constraints.

Actually what I originally set out to do and would prefer is to simply 
change the angle of the parent space of a child null which is the jaw 
control (we call them "movers" here). The jaw control needs to be freely 
transformable.

This I was able to do by having a custom property just rotate a parent 
null by, say 50 degrees, and the jaw control null to -50 degrees. Then 
the Y trans of the child null (the jaw control) can drop at a different 
angle when needed.

This works perfectly, except that I lose control of the rot X of the jaw 
mover. I can't find a way around it and it seems like it should be a 
really easy problem.

Thanks,
