It should... The demo video was done using Timeline. If you haven't tried loading as a session plugin before anything else, I'd recommend that first. Otherwise if you post how you're using it I can take a look at some point.
It adds the same controllers you use to move other joints around to the fingertips and tongue, so you can control them directly rather than using morphs. A video's on the to-do list...
I'm already VERY into this as a concept! Dunno about tongues, but Finger controllers would be LIFECHANGING for my stuff!! I'll keep a very close eye and this and wish you the absolute BEST of luck developing this!!
