I assume that you want this for a dynamic effect, because if the redish cheeks are fixed then I would recommend painting it straight onto the texture.

Jessy explains the fundamentals of writing custom shaders fantastically. Without these videos I wouldn't be able to write any sort of shaders! I am eternally grateful to Jessy (if he's reading) :-)
