If the Channel Box is not visible, open it (hotkey: Shift+C ). A Spot light named spotLight1 is created at the scene's origin point. Reset the values to their defaults (Edit Reset Settings), and click the Create button. You can also access these attributes in the Attribute Editor. Open the Hotbox and click Create Lights Spot Light option box to open the Create Spot Light Options dialog box, which contains basic creation options for the Spot light. You'll see three primitive objects, a wall, and some ground for the objects. Start Maya, and open the scene file from the Maya Fundamentals CD-ROM (noted below the CD icon). Spot lights are useful when you're trying to create conic beams of light from, for example, a prison watch tower, a lighthouse, and so forth. Starting from an infinitely small point in space, a Spot light spreads as it moves farther from the origin.
The Spot light's area of illumination is defined by a cone, and within the cone's specified range, light is cast evenly. The first light you'll work with is the Spot light, probably the most commonly used light, with a multitude of options to adjust the settings for the areas it illuminates. By using a simple scene with some NURBS primitives, you can create lights and render them to see the results of changes in attributes and other settings. To learn to use lights, you need to work with them interactively. Different icons identify the lights in your scene. Each one has its own icon to represent it in your scene (see Figure 9.1). Several different lights are available in Maya 4, each with its own properties and uses: Directional, Ambient, Point, Volume, Spot, and Area lights.
