Part XI: Advanced Lighting and Rendering
1. Open the Clouds.max file from the Chap 46 directory on the DVD.

This file includes several hemispherical-shaped Atmospheric Apparatus gizmos.
2. Choose Rendering ➪ Environment (or press the 8 key) to open the Environment and Effects dia-
log box. Click the Background Color swatch, and select a light blue color. In the Atmosphere sec-
tion, click the Add button, select Fire Effect from the Add Atmospheric Effect list, and click OK.
3. Name the effect Clouds, click the Pick Gizmo button, select each of the Sphere Gizmo objects in
the viewports, and then click on each of the color swatches. Change the Inner Color to a dark
gray, the Outer Color to a light gray, and the Smoke Color to white. Set the Shape to Fireball with
a Stretch of 1 and a Regularity of 0.2. Set the Flame Size to 35, the Flame Detail to 3, the Density
to 15, and the Samples to 15.
Tip
If you want to add some motion to the clouds, click the Animate button, drag the Time Slider to the last frame,
and change the Phase value to 45 and the Drift value to 30. The clouds slowly drift through the sky. Disable the
Animate button when you’re finished. n
4. In the Fire Effect Parameters rollout, click the Pick Gizmo button and then click one of the giz-
mos in the viewports. Repeat this step until you’ve selected all the gizmos.
Figure 46.10 shows the resulting sky backdrop. By altering the Fire parameters, you can create different
types of clouds.
