Re the JMC dials. I'd suggest visible, but in a rolled up group (collapsed 1). Unless something has changed in recent versions of Poser, reading the deltas in a targetGeom channel when the figure loads will force the dial to show, even with a normal 'hidden 1'. You can partially get round that by by placing 'hidden 1' after the deltas, but it won't survive a save and reload.

Quote - Les?  Anyone?  Ever worked with parameter group injection poses?

Everyone says they are destructive, overwriting any existing groups, and I have no information to the contrary.

I agree with what Cage says about the foot, and think the the foot is probably weakest part of Antonia's rig at the moment. With a bend of -30, the ankle has an obvious crease. There are also some problems at the foot/instep boundary, where there seems to be a complicated interaction between JPs and JCM. Moving the joint centre up seems to help a lot at the foot/instep boundary, but as that also affects the way the foot bends at the ankle, I'm not sure which is worse the disease, or the cure.
