tensity of the colors painted on the surface to determine which parts have stronger specular reflection than
others. We will use this technique to make the Enforcer's leather corset appear worn and well-used.
The Material Mixer
The Material Mixer's function is to determine how shaders within a material are layered on top of each
other. The advanced settings at the bottom of the Mixer offer controls that set criteria for the strength of the
shader based on everything from shadow strength to the hue, intensity, or saturation (or any combination) of
the colors painted on the surface. Using these controls, you can create some pretty amazing material effects.
This tutorial is going to keep things fairly simple. You will create a two-shaded material: One shader will
be very diffuse and the other, very specular. Then you will set the Mixer up so that the specular material is
stronger on the parts of the surface that are darker in color and the diffuse shader is stronger on the parts of
the surface that are lighter in color. This creates a realistic effect since rough surfaces tend to diffuse reflec-
ted light, making them appear lighter than reflective surfaces. Think of a worn leather jacket: the crevices,
which are not as exposed to wear and tear, tend to be smoother and shinier than the exposed parts, which
become rougher and lighter in color.
1. Open the latest version of the project.
2. In the SubTool stack, find the SubTool named “corset.” Select this SubTool and turn on the Solo button,
so that the other SubTools are hidden. Set the SDiv slider to the highest setting (see Figure 10-31 ).
