Bump Map

This was the final level of detail to add to the model. The bump map adds dips and bumps on the texture to make it look more realistic and lifelike.

This was achieved by first making a copy of the texture. By turning the texture into a greyscale image using the Desaturate tool, and then using the Levels tool to highten the light areas and darken the shadowed areas, I had created the first steps of the bump map.

The next stage entailed using the high pass function. By using this, I was able to extrude/bevel the details of the face, which I could then use in 3Ds Max to heighten the effects of the material. I ran into a problem with this almost immediately, as the neck skin had mostly been created with brush strokes, there was no detail to be applied to it, leaving a very strange smoothness which the rest of the model didn't have.

To fix this, I cloned some of the bump map from the forehead and face onto the next, thus fixing the issue. Here is the finished article.
