3. Material Rendering (Skin)
Game renderers are often required to generate a range of material effects (from hard surfaces such as wood or granite, to softer surfaces such as soil, leather, or skin).
Some types of material can be adequately renderer using a straightforward combination of diffuse, normal, specular, height/bump maps.
More sophisticated materials typically require specially developed shaders.
