Face extraction need help


I’m playing around with ofx face tracker for couple of days, and it’s a Wonderfull thing ! thanks for that.
I’m almost reaching my goal, I need to extract my face from the tracking, Thanks to the face extraction example, I’m done with it, but I still have an issue : I want to modify the shape I get from the example : right now, the eyes and the mouth are masked. I’d like to modify this shape, at least to have the eyes and mouth as well captured on the texture. Could you point me out the place to modify this mask/mesh ? I’ve been trying to comment out plenty of part of the code, but I still didn’t find where this gabarit is draw.

Thanks a lot,
