Hi all

I am in the midst of rendering / texturing my 3D head mesh with the objective of photorealism. I've applied fast skin, Brownian 3D and hair and eye / eyebrow and its looking good. I use PaintFX for the eyebrow and convert it to polygon. I would like to know how to texture/shade/render the lips and eyelid / eye lining area which is normally darker than the facial tone. I am not using UV mapping but directly applying Maya's generic shaders from Hypershade which I think give more realistic and better results. Any ideas ?

Thank you in advance.
