Two questions after finished RGB fitting script

[slime898]

Thank you for release your awesome project. I am novice of 3D reconstruction, and want to ask two questions after finished RGB fitting.

First question is, if I want to change the color of the eyebrows of generated 3D face after finished RGB fitting script, It seems that I can only manually check which faces belong to the eyebrows, then change corresponding pixels on texture picture by UV coordinates. Do I ignore anything or maybe you can teach me which faces belong which parts of generated 3D face ?

Second one is, if the above is true, can you teach me how to find corresponding pixels on the texture by 3D vertices ?

A feasible solution is to use 3D software (e.g., R3DS Wrap) to find the face indices of the eyebrows, and then find the corresponding UV coordinates based on these face indices.
