Anisotropy Controls the anisotropy, or shape, of this highlight. At 0, the highlight is round. At 100, the highlight is extremely narrow. One axis of the Highlight graph changes to show changes in this parameter. Default=0. Orientation Changes the orientation of this highlight. The sample slot shows changes in orientation. This is a value in degrees that can range from 0 to 9,999. Default=0. Highlight graph These two intersecting curves show the effect of adjusting the values of Level, Glossiness, and Anisotropy. As you decrease Glossiness, the curves grow wider; as you increase Specular Level, the curves grow taller. As you adjust Anisotropy, the white curve changes to show how wide or narrow the highlight is. Translucent Highlights Material Editor > Standard material > Translucent Basic Parameters rollout > Specular Highlight group Like the Blinn shader, the Translucent shader has circular highlights. Procedures To increase or decrease the strength of a highlight: ■ Change the value of Specular Level. The intensity of the Highlight curve and the highlight in the preview change. At 0% specular level, there is no highlight. At values greater than 100%, the curve is overloaded: it grows wider, and a wider area is at the maximum highlight intensity. At 100% specular level, the curve is at its maximum height with no overloading. The shape of the Highlight curve affects the blending between the specular and diffuse color regions of the material. The steeper the curve, the less blending there is and the sharper the edge of the specular highlight. To increase or decrease the size of a highlight: ■ Change the Glossiness value. The width of the Highlight curve and the highlight in the preview change. At 0% glossiness, the curve is at its maximum width. At 100% glossiness, the curve is extremely narrow.
