The title is rather self-explanatory.

By making a script for the Cubism editor, it can help simplify the extras that facerig needs and automate it for less experienced creators (ie myself. Reading the documentation is rather difficult and I'm still working through video tutorials which spend more time talking about the NEW FEATURES than what I want to know.)

By adding Dual Camera support, you can solve the issue of body-tracking as a seperate component, or even allow for unique effects like cutaways or 360-degree movement, or fix the face tracking's issues like it constantly losing track of where it is.
