Looking at the tutorials on the animation and rigging toolkit I got the feeling that the toolkit will expand over time. Are there any plans on including the facerig system made for GoW3?
Cheers
Found this on twitter, looks like Ernst already is working on it! Great!
@mattanimation Thanks man! I can't wait to add more! Facial rigging tools coming next!

It is currently being worked on!
I’ve created a master thread that will detail FAQs, Known issues, and upcoming features as well as the latest code drops:
any news on the facial rig?
And here we are in 2017… 
nov/18, we will have the facial rig tool with Artv2?
