Although moving the lThigh_smooY channel seems to solve the worst symmetry problem, I'm not convinced that it is a better idea than just deleting the smoothScale channels. I have come to hate smoothScale with a vengeance, and if it were me, I would probably delete all the smoothScale channels.

The symmetry problems came to light because I was trying to make some ERC based scaling for Antonia. This has proved more difficult than I had expected. The scaling ERC is in itself fairly trivial, but there are various issues to do with the JPs that arise due to scaling, and which need to be dealt with if the scaling is ever to be a practical concern. It's not just the smoothScale channels. The 'joint' channels each seem to have their own private joint centre specified in the 'center' line of the channel, and whilst the origins of the actors move appropriately with the scaling, these private joint centers do not, they remain in the original location. I feel that I am making slow progress with the ERC scaling, but have had to make some additional JCM, and some JP poses to correct problems.

Getting back to the subject of smoothScale. The neck is another place where I am finding the smoothScale less than helpful, see image above. For my ERC scaling pose I'm going to see if I can disable all the smoothScaling by setting the 'otherActor' to NULL.

Calling cage.
The neck is the most problematic actor I have come across so far. Cage, I understand that you have been working on some new JPs for a longer neck, and would appreciate any advice you may have on that subject.
