Left Corner Mouth Widget Control

I revised my idea for the face UI I was working on. Instead, I created a left corner mouth widget maker. It creates a controller for the left corner of the mouth. All you need to do is add your blendshapes to the text fields, name your blendshape, and press the buttons as you go down the UI. I coded about 50% of the tool and need to work on the remaining portion. It works pretty smoothly. It will build a corner controller, make the deltas needed when two shapes are turned up to 1, and rebuilds the blendshapes but adds a node selection system to know how much weight of the blendshape to trigger depending on where you are on a square controller. I will post a demo once I finish coding the remaining half. My test was successful on dummy shapes I used for the Base, Mouth Up, Smile and Mouth Wide shapes. I will need to code one for the right mouth corner once I finish this portion. Version 1.0 will be the closed mouth version of the widget. Version 2.0 will add the mouth open function and I will have to adjust for the mouth opening as the jaw control is rotated. This widget is great if you can't use a plugin such as the Blendshape Combination System. For me, it was a great way for me to learn how to have two blendshapes at value 1 but trigger the desired shape you want rather than the typical blendshapes resulting from the additive behavior in Maya.
