Hello,
I bought facefilter3 pro in order to morph or reshape some faces for a scientific experiment.
The program is working very well.
I am just wondering what kind of measurement units are being changed when I´m "reshaping" for example the mouth to " -20 ".
What kind of measurement unit is meant with the number "-20".
Another question would: is there any possibility to change the pixel units wen reshaping?

I would be more than happy if I could get some answers. Thank you very much!
