Dim Level The amount of dimming that takes place in shadow. At 0.0, the reflection map is completely dark in shadow. At 0.5, the reflection map is half dimmed. At 1.0, the reflection map is not dimmed and the material appears as if Apply were turned off. Default=0.0. Refl. Level Affects the intensity of the reflection that is not in shadow. The Reflection Level value multiplies the illumination level of the lit area of the reflection, to compensate for dimming. In most cases, the default value of 3.0 keeps the reflection in the lit area at about the same level it would appear if reflection dimming were not on. Maps Rollout (Standard Material) Material Editor > Standard material > Maps rollout A material's Maps rollout lets you access and assign maps on page 8036 to various components of the material. You can choose from a large variety of map types. To find descriptions of these types, and how to set their parameters, see Map Types on page 5767. Assigning the Same Map to Different Parameters Applying the same map to different parameters is useful in some cases. For example, using a pattern to map both self-illumination and opacity can make the pattern appear to glow and hover in space. Blending Map Amounts for Opacity and Other Material Components When you map a scalar component (such as Specular Level, Glossiness, Self-Illumination, and Opacity), the component's value in the Basic Parameters on page 5406 rollout is blended with its associated map Amount in the Maps rollout. For example, when the Opacity spinner is set to 0, the map Amount spinner completely controls Opacity. That is, reducing the Amount value increases the transparency of the entire surface. On the other hand, when Opacity is 100, reducing the map's Amount value increases the opacity of the entire surface. You can adjust a Checker Opacity map so that the opaque areas remain opaque, while the transparent areas become semi-transparent. Other scalar components behave in the same way. Setting the map's Amount to 100 applies all of the map. Setting the Amount to 0 is the equivalent of 5414 | Chapter 19 Material Editor, Materials, and Maps
