Rendering the Enforcer - ZBrush Creature Design: Creating Dynamic Concept Imagery for Film and Games - page 665

To create a single material form the Diffuse, Specular, and SSS shaders, you will copy each shader into one
of the slots of the TriShader material and then use the Mixer to control the amount of influence each shader
has on the material itself.
1. Continue with the project from the previous section. Make sure that the Diffuse shader, Specular shader,
and SSS shader are all loaded into ZBrush. If they are not, you can use the Load button in the Material
palette to load them from your local disk.
2. Select the Diffuse shader and press the CopySH button in the Material modifiers.
3. Select the TriShaders Material from the Material palette, don't worry about the way the model looks at
the moment—it will update as you switch materials. Select the S1 button at the top and press the PasteSH
button to paste the Diffuse shader into the first slot of the TriShaders material ( Figure 10-18 ).
Figure 10-18: Copy the S1 shader from the Diffuse shader. Use the PasteSH button to paste it into the S1
slot of the TriShaders material.
4. Repeat these steps to paste the S2 shader of the SSS Shader into the S2 slot of the TriShaders material
and then the S1 shader of the Specular shader into the S3 slot of the TriShaders material.
5. Save the material as enforcerSkin.ZMT.
Next, you'll do a little tweaking to get the three shaders to work together a little better.
6. Press the BPR button on the right shelf (hot key = Shift + R) to create a render. The left image in Figure
10-19 shows the result. At this point, it is not completely convincing. The SSS effect is too strong, result-
ing in a red fringe around the edges.

Modifies subpalette of the Material palette.
