The *Control Window* is sometimes referred to as the *Environment Editor, Shader Editor, Texture Editor, or Light Editor*.	The *Control Window* is the interface you use to edit shaders, textures, lights, and the environment. You can also use the *Control Window* to access the *Color Editor. In This Section: Control Window Overview* 34 Copying Parameter Settings 39 Animating Parameter Settings 40 Control Window Overview

	The *Control Window* contains a list of parameters for the selected swatch in the *Multi-lister, and allows you to edit these parameter values or settings interactively. There are four different types of Control Window*: environment, shader, texture, and light.

	For more information on each type of *Control Window* see: Environment Parameters on page 55. Shader Parameters on page 74. Texture Parameters on page 101. Light Parameters on page 237. *To open the Control Window for a shader, texture, light, or for the environment, do one of the following:* Double-click the environment, shader, texture, or light swatch in the *Multi-lister, or Click on the environment, shader, texture, or light swatch in the Multi-lister, and select Edit > Edit* in the *Multi-lister. Title Bar The title bar indicates the name of the active environment, shader, texture, or light in the Multi-lister. It also contains buttons or icons that let you set a keyframe for a parameter, or scroll through the Multi-lister* swatches. Parameters Parameters control the appearance of shaders, textures, lights, and the environment. Each parameter has a name, which describes the parameter, and a field, which specifies (and allows you to change) the parameter's setting or value. The *Control Window* contains several different types of fields: name fields, file name fields, toggle fields, menu fields, numeric fields, and color fields. Name Fields Name fields let you change a shader or texture name by clicking in the field and typing a new name. Textures also have an arrow button on the left side of the name field, and ON and *OFF* buttons on the right side of the name field. The arrow button lets you select the texture's parent swatch in the *Multi-lister* (that is, the environment, shader, texture, or light that the texture is mapped to). The ON and *OFF* buttons let you turn the effect of the texture on or off. File Name Fields and Browse Buttons File name fields let you specify a path and file name by clicking in the field and typing a file name. File name fields also have a *Browse* button on the right side of the field. You can click the *Browse* button to select a file using the *File Requestor. Toggle Fields Toggle fields let you set a parameter ON or OFF. Menu Fields Menu fields let you select from a list of menu options by clicking the mouse on a menu button, and then releasing the mouse on the desired option. Numeric Fields Numeric fields let you enter a number using either the keyboard or a slider beside the field. Each numeric field has a valid range (the range of values you can enter by typing in the field) and a slider range (the range of values you can enter using the slider). The slider range represents the recommended range of values for that parameter. The valid range is -· (negative infinity) to · (positive infinity) for all numeric fields unless otherwise stated. Some numeric fields also have a Map* button (for example, *Reflectivity). Color Fields and Map Buttons Color fields let you specify the color value* by using the slider, specify the color by clicking the color field and opening the *Color Editor, or map a texture to the parameter by clicking the Map* button. If you map a texture to a color field, a red arrow button will appear to the right of the *Map* button. By clicking this red arrow you can open the *Control Window* for that texture. Parameter Groups Parameters are organized in groups in the *Control Window. You can display or hide a parameter group by clicking on the group name. Copying Parameter Settings*

	You can copy parameter settings from one environment, shader, texture, or light to another. *To copy parameter settings from one environment, shader, texture, or light to another:* 1 Open the *Control Window* for the shader you want to copy parameter settings from (for example, *Shader). 2 Hold the Shift key and click the shader swatch for the shader you want to copy parameter settings to (for example, Shader#2). 3 In the Control Window, hold the Shift* key and click on the names of the parameters you want to copy (for example, *Color* and *Transparency*). The parameter names become highlighted.
See Copy Parameters on page 26.	4 Select *Edit > Copy Parameters* in the *Multi-lister. The parameter settings are copied (from Shader* to *Shader#2). 5 Shift-click the parameter names again to deselect them. Animating Parameter Settings*

	You can animate an environment, shader, texture, or light parameter by creating key frames for the parameter. *To create a keyframe for a parameter:* 1 Hold the Shift key and click the name of the parameter you want to animate (for example, *Color). The parameter name becomes highlighted. 2 Go to the frame of your animation that you want to create a parameter keyframe for. 3 Adjust the parameter setting or value for that frame. 4 Click the Key* button in the title bar of the *Control Window. A white diamond (animation icon) appears in the Control Window* beside the parameter name, and in the *Multi-lister* swatch. These icons indicate that a parameter is animated. 5 Shift-click the parameter name again to deselect it. *To play back an animated environment, shader, texture, or light in the Multi-lister:* Click-hold the animation icon in the lower left corner of the environment, shader, texture, or light swatch in the *Multi-lister*.
