I have been playing with the mentalray Miss_Skin_Maya shader for Maya for some time. This is what I found to setup realistic skin material. Im here to share my experience with you. I know that this is still under construction stage and I will improve it for better result. This is not the best and will always be a better way of doing it. If you have a different point of view or have anything add to it please feel free.
This tutorial is currently in English. I'll "try" to translate into Chinese when Im not lazy.
The character for this demonstration is Maurice. I did the base model and UV in Softimage, detailing in Zbrush, texture in Photoshop CS4(very nice with the new 3D mode) and finally back to Maya for rendering.
