4. Set Vein Spread to 0.5, Layer Size to 0.5, Randomness to 1.0, Age to 10.0, and Grain
Contrast to 0.33. In the Noise Attributes heading, set Amplitude X to 0.2 and Ampli-
tude Y to 0.1, as shown in Figure 7.102. Name the shader
wood
.
5. Select all the wood railings and posts, and assign the Wood shader to them. Render
a frame, and compare it to Figure 7.103. Notice the green cube place3dTexture node
that is now in your scene. (See Figure 7.104.)
6. The side wood railings look fine; however, the wavy pattern on the front and back
wood railings looks a bit odd. In the Hypershade, duplicate the shading network for
the Wood shader, and call the new shader
woodFront
.
7. Assign that shader to the front and back railings and posts. Graph the network on
the woodFront shader in the Hypershade window.
