How can I achieve 2D projection facial rigging in Maya like this?



I saw this open source technology on this website:

But when I follow the instructions to this step「Building the VRay Plugin」
I am stuck here :frowning: Because I’m just a maya animator and don’t have any programming skills.

But I really need this feature, how can I achieve similar Rigging in Maya?
(2D facial projection rigging + moveable & scaleable)

If this requires Phython or Rigging technology, I can also try to learn.
or is there any script or plug-in that can achieve this effect?

many thanks!
