Making the Specular Map

Not only is skin not perfectly smooth, but it is also shinier in some places more than others. A specular map can be created to improve the realism. Using a copy of the bump map from before, using image > adjustments > levels, it has been made much darker. A soft brush is then used to paint white onto the parts of the face that should be shiny. The forehead, chin, cheeks and lips are often touched by the hands making them greasier, therefore shinier.

With the relevant places made whiter, it is then blurred by going to filter > blur > gaussian blur.

Back in 3DS Max, this new image is applied to the specular parameter in the maps rollout in the skin material. The images below show the model with all of the required steps complete.
