Nice modeling and the colours look good ,the braces look a bit fierce though ,glad Im past that stage lol,you ever thought of donating a set of gums/teeth models
If you got the fac rig/the AMtrack and the BVH settup it would be a absolute magical rig .Its allready dam good but that would be terrific Mark.And its definitely not a waiste of time ,More and more ppl are using it .I think it takes a lot of time before ppl change from one rig to another that theye don't know
Just gave it a go in v150f and it seems to work fine ,I just used the top cp's and made them 50% ONE BONE AND 50% the other,I just used the done button after selecting in the modeling window
