swatches and parameters take you to the Material/Map Browser on page 5290, where you select a map of corresponding type. These are shortcuts that also have corresponding buttons in the Maps rollout. If you have assigned a map to one of these colors, the button displays the letter M. An uppercase M means that the corresponding map is assigned and active. A lowercase m means that the map is assigned and inactive (turned off). Shading drop-down list Chooses a shader. Depending on the shader you choose, the Specular Highlight can change to show the controls for that shader. The alternatives are: ■ Anisotropic: on page 5449 For surfaces with elliptical, "anisotropic" highlights. ■ Blinn: on page 5451 For rounder, softer highlights than Phong shading. ■ Metal: on page 5452 For metallic highlights. ■ Oren-Nayar-Blinn: on page 5451 For matte surfaces such as fabric or terra-cotta. ■ Phong: on page 5451 For surfaces with strong, circular highlights. Phong is the default shading type. 2-Sided Same as for standard materials. When on, shades and raytraces both sides of faces. By default, objects are one-sided in order to speed up rendering. If you have a 2-sided, reflective and refractive object, and you use the raytrace map on page 5952 rather than the material, the raytracer runs until it hits the maximum recursion level. This can be time-consuming. Wire Same as for standard materials. When on, renders the material in wireframe mode on page 8172. You can specify the wire size in the Extended Parameters rollout. With pixels, wires maintains the same apparent thickness regardless of the scale of the geometry or how near or far the object is positioned. With units, the wires appear thinner at a distance and thicker at close range, as if they were modeled in the geometry. Face Map Applies the material to the faces of the geometry. If the material is a mapped material, it requires no mapping coordinates on page 8034. The map is automatically applied to each facet of the object. Faceted Renders each face of a surface as if it were flat. NOTE Raytrace material has the same SuperSampling on page 5381 options as a Standard material. 5494 | Chapter 19 Material Editor, Materials, and Maps
