The button to the right of the image preview area is used to apply a texture instead of an image. Textures and texture editing are discussed later in this chapter. When an image, such as a bitmap image or digital photograph, is applied, the material color is replaced with the image. Figure 17-10 shows an object with a computer screen image applied to the material attached to it. The Image Fade property controls the ratio between the image and the object color. When set to 100, the image completely replaces the object color. The Glossiness property controls how shiny the material appears, Figure 17-11. It is a measure of the surface roughness of a material. A setting of 100 specifi es a very shiny material, such as a smooth surface. A setting of 0 specifi es a matte (dull) mate- rial. The button to the right of the setting allows you to add a texture or image to the Glossiness property. The pattern is applied to the glossiness effect. Reflectivity must be turned on for the glossiness effect to be seen. Refer to the next section. The Highlights property determines how the shiny areas are created. Choices for this property are Metallic or Non-metallic. Highlights are brighter when Metallic is selected. A B C Glossiness = 25 A Glossiness = 50 B Glossiness = 75 C Figure 17-10. A material with an image applied instead of a color to simulate a tablet screen. A—The screen object’s material does not have an image applied. B—A bitmap image has been applied to the image component of the screen object’s material. C—The finished tablet. Figure 17-11. Three different glossiness settings are illustrated here.
