Well you could have heard a pin drop when I showed the new BlenRig tool to my colleges. The ease at which this powerful set of body and facial rigging tools can be set up and used to animate edge loops is awesome. I plan to start adding the BlenRig tutorial links here as they get added t YouTube by the guys at Blender cloud. To start your rigging adventures Download Blenders latest here https://www.blender.org/download/ and then the plugin at https://gitlab.com/jpbouza/BlenRig
There is a bunch of tutorials to be found on YouTube. If you don't know Blender don't despair. There are tones of forums and videos about the place to get you up to speed.
