NOTE For the Raytrace material on page 5490, the Specular Color component appears in the Specular Highlight group. Also, highlight controls that don't pertain to the current shader are labeled "N / A." Procedures To increase or decrease the size of a highlight: ■ Change the Glossiness value. The width of the Highlight curves and the highlights in the preview change. At 0% glossiness, the curves are at their maximum width. At 100% glossiness, both curves are extremely narrow. To increase or decrease the strength of a highlight: ■ Change the value of Specular Level. The intensity of the Highlight curves and the highlights in the preview change. At 0% specular level, there is no highlight. At 100% specular level, the curves are at their maximum height with no overloading. At values greater than 100%, the curves are overloaded: they grow wider, and a wider area is at the maximum highlight intensity. The shape of the Highlight curves 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 adjust the shape (anisotropy) of the highlight: ■ Change the value of Anisotropy. The width of the white highlight curve and the highlights in the preview change. At 0% anisotropy, both highlight curves are the same and the Standard Material | 5449
