value. The Paint Levels value sets the number of colors that are used to color the material. The Glossiness
value determines the size of the highlight. Figure 30.2 shows materials with Paint Level values of 2–6.

Use the Paint Level value to set the number of colors used in the material.
The Ink Controls rollout includes an Ink option that you can use to turn off the outlining ink completely.
You also can set the Ink Quality to values between 1 and 3. The higher-quality values trace the edges better,
but require more time to complete. The width of the ink strokes can be set to Variable Width or a Clamped
width. For each option, you can select a Minimum ink width, and if Variable Width is enabled, you can
choose a Maximum ink width. For the Variable Width option, the stroke changes so that the minimum set-
ting is used in lighted areas and the maximum width is used in shaded areas. This helps to accentuate the
lighting. You can also apply the ink width as a map. Figure 30.3 shows the Ink ’n’ Paint material applied to
a cube. The first image shows a standard material; the second image has the Ink option disabled. The last
three images have Width values of 1, 10, and 30.

Tip
Placing a noise map on the Ink Width property is a great way to give the ink outline a hand-drawn look. n

The rest of the options in the Ink Controls rollout are enabled to control where the ink is applied to the
object. Options include Outline, Overlap, Underlap, Smoothing Group, and Material ID. For each of these
options (except for Smoothing Group), you can alter a Bias value that can adjust intersecting edges. Each of
these options can be applied as a map.

Tutorial: Cartooning a turtle
As an example of the Ink ’n’ Paint material, you’ll render a cartoonish turtle model created by Zygote Media
as a cartoon that is fit for the Sunday papers.
To apply the Ink ’n’ Paint material to a turtle model, follow these steps:
1. Open the Cartoon turtle.max file from the Chap 30 directory on the DVD.
This file includes a simple turtle model.
2. With the turtle model selected, open the Material Editor by choosing the Rendering ➪ Material
Editor ➪ Slate Material Editor menu command (or by pressing the M key).
