Figure 17.24 shows the Splat map with a Size value of 60, 6 Iterations, and Threshold values of (from left to right) 0.2, 0.3, and 0.4.
FIGURE 17.24
The Splat map splatters paint randomly across the surface of an object.
Stucco map
The Stucco map generates random patches of gradients that create the look of a stucco surface if applied as a bump map. In the Stucco Parameters rollout, the Size value determines the size of these areas. The Thickness value determines how blurry the patches are, which changes the sharpness of the bumps for a bump map. The Threshold value determines how much of each color to mix. The rollout also includes two colors for the patchy sections, or you can load maps instead.
Figure 17.25 shows the Stucco map with a Threshold value of 0.5, Thickness of 0.02, and Size values of (from left to right) 10, 20, and 40.
FIGURE 17.25
The Stucco map creates soft indentations when applied as bump mapping.
Cross-Reference
Procedural textures are created with the Substance map, which is covered in Chapter 31, “Working with Procedural Substance Textures.” •
Waves map
This map creates wavy, watery-looking maps and can be used as both a diffuse map and a bump map to create a water surface. You can use several values to set the wave characteristics in the Water Parameters rollout, including the number of Wave Sets, the Wave Radius, the minimum and maximum Wave Length, the Amplitude, and the Phase. You can also Distribute the waves as 2D or 3D, and a Random Seed value is available.
Figure 17.26 shows the Water map with the Num Wave Sets value set to (from left to right) 1, 3, and 9.
FIGURE 17.26
You can use the Water map to create watery surfaces.
Wood map
The Wood map produces a two-color wood grain. The Wood Parameters rollout options include Grain Thickness, Radial, and Axial Noise. You can select the two colors to use for the wood grain.
Figure 17.27 shows the Wood map with Grain Thickness values of (from left to right) 8, 16, and 30.

The Wood map creates a map with a wood grain.
Compositor maps
Compositor maps are made by combining several maps into one. Compositor map types include Composite, Mask, Mix, and RGB Multiply.
Composite map
Composite maps combine a specified number of maps into a single map using the alpha channel. Each separate map is listed on a separate layer, and the layers are composited from the top layer down. The Composite Parameters rollout lists the number of layers and includes a button for adding a new layer, as shown in Figure 17.28.
Each layer has preview swatches for specifying a texture and a mask. To the side of these preview swatches are buttons for hiding the layer or mask and for color correcting each. There are also buttons for deleting, renaming, and duplicating each layer.
FIGURE 17.28
The Composite Layers rollout lists each composite map as a separate layer.
The Opacity value sets how transparent the layer is, and you can also change the blending mode using the drop-down list at the bottom of each layer. The blending mode defines how the texture on the current layer is combined with the layers below it. The available blending modes include Normal, Average, Addition, Subtract, Darken, Multiply, Color Burn, Linear Burn, Lighten, Screen, Color Dodge, Linear Dodge, Spotlight, Spotlight Blend, Overlay, Soft Light, Hard Light, Pinlight, Hard Mix, Difference, Exclusion, Hue, Saturation, Color, and Value.
Note
Composite maps and blending modes in 3ds Max 2009 work similar to layers in Photoshop. •
Figure 17.29 shows three different uses for the Composite map. The left image combines a Checker map with a Gradient map. The last two images combine a Swirl map with Checker and Cellular maps.
FIGURE 17.29
The Composite map can use multiple maps.
Mask map
In the Mask Parameters rollout, you can select one map to use as a Mask and another one to display through
