Anyway, all the really fantastic improvements get eclipsed by the shine of Smart Bones, and this feature becomes the main reason I think everyone (seriously, everyone) should upgrade to 9.
I have been working with AS9 for a while and I have made a lot of rigs with it. I know there are some videos showing how you can create smart bones and for what can be used for, so I won't show you tutorials, I just want to share some of the rigs I have been working on, I think they could inspire you.

PD: I'll be posting more videos on this thread.
