Tutorial: Draping cloth over a jet
For a larger example of a cloth system, you'll drape a drop cloth over a jet.
To simulate the dynamics of a cloth object, follow these steps:
1. Open the Sheet over Mig jet.max file from the Chap 44 directory on the CD.
This file includes a Mig-29 jet model created by Viewpoint Datalabs.
2. Choose the Create⇒Standard Primitives⇒Plane menu command, and drag in the Top viewport to create a plane object that covers the jet. Set the Length and Width values to 150 and the Length and Width Segment values to 100 to make the sufficient resolution for the cloth, and drag the plane object upward in the Front viewport, so it sits above the jet.
Note
You also can create the cloth from a rectangular spline that has the Garment Maker modifier applied to it. This approach uses the Delaunay tessellation, which is better for simulating cloth than the rectangular sections in the Plane object. •
3. With the plane object selected, choose the Modifiers⇒Cloth⇒Cloth menu command to apply the Cloth modifier to the object.
4. Open the Modifier panel, and click the Object Properties button in the Object rollout to open the Object Properties dialog box. Select the Plane01 object in the left list, and choose the Cloth option. Then select the Silk option from the Presets drop-down list, and set the Thickness to 0.5.
5. With the Object Properties dialog box still open, click the Add Objects button, click the Select All button, and click the Add button. With all added properties in the left list selected, choose the Collision Object option and click OK to close the dialog box.
6. In the Simulation Parameters rollout, enable the End Frame option and set the end frame to 100. Then click the Simulate button in the Object rollout. The plane object descends and covers the jet being draped as it falls.
Figure 44.6 shows the sheet draped over the jet.

Summary
Using dynamic simulations, you can control and compute the motions of hair, fur, and cloth. These motions take into account the various forces and collision objects included in the scene.
Specifically, this chapter covered the following topics:
• Enabling hair dynamics
• Simulating cloth dynamic motion by initiating a simulation process
Part XI, “Advanced Lighting and Rendering,” is up next. It includes coverage of several advanced topics beginning with the advanced lighting options.

If you were to walk into a dark room and reach for the light switch, you would be confused if you found a separate switch that controlled the advanced lighting. But in Max the advanced lighting controls are worth the trouble. They enable you to take your lighting solution to the next level.
The advanced lighting controls in Max enable you to light scenes using two separate global illumination techniques known as light tracing and radiosity. Both solutions deal with the effect of light bouncing off objects and being reflected to the environment.
