Copyright Goodheart-Willcox Co., Inc. Chapter 17 Materials in AutoCAD 461 Texture Editor The texture editor is used to adjust a map once it has been applied to a material property. It is automatically displayed once a map is assigned. Figure 17-23 shows the texture editor with an image map displayed for editing. A preview of the map appears at the top of the texture editor. The triangle in the lower-right corner of the preview is used to resize the preview. Below the map preview, the type of map is indicated. Maps rarely appear on the object in the correct position, scale, or angle. For example, if you are using an image map of a logo to be applied to a box for a packaging design, it may not be positioned in the center of the box by default. The map may be rotated in the wrong direction or it may be too large. The texture editor is where adjustments to the map are made. The bottom of the texture editor contains the settings for the map. The properties that are available depend on the type of map being edited. As shown in Figure 17-23, the Transforms, Position, Scale, and Repeat categories are available and automati- cally expanded when the texture editor is opened for an image map. The next sections discuss the properties for each map type. Image Applying an image map is straightforward. There are several fi le types that can be applied as a map. When you specify Image as the map for a property, a standard open dialog box is displayed. Navigate to the image fi le and open it. In the texture editor, the preview area shows the image with dimensions for the size of an individual tile. If the Sample Size property in the Scale category is changed, the preview dimensions refl ect the change. Directly below the preview are the image fi le name and a slider/text box for adjusting the image brightness. Refer to Figure 17-23. To select a different image, pick the name to display a standard open dialog box. A brightness value of 100 means the image is at its full brightness. A value of 0 results in the image being all black. The check box below the slider is used to invert the image colors. This produces an effect similar to a photographic negative Map preview Map type Pick to select a different image Adjust the image brightness Set the position and rotation Set how the map is repeated Set the scale (size) Figure 17-23.
