1478 Chapter 16: Material Editor, Materials, and Maps
Inter face
The Maps rollout contains a wide button for each
map type. Click this button to select a bitmap file
stored on disk or to select a procedural map type
(page 3–997) . After you select a map, its name and
type appears on the button. Use the check box to
the left of the button to turn the effect of the map
off and on. When the check box is off, the map is
not computed and has no effect in the renderer.
The Amount spinner determines the amount
that the map affects the material expressed as a
percentage of full intensity. For example, a diffuse
map at 100% is completely opaque and covers the
basematerial.At50%,itissemi-transparentand
thebasematerial(thediffuse,ambient,andother
colors of the material without mapping) shows
through.

number of components that can be mapped varies
depending on the current shader (page 2–1466).
The last four rows are always Bump, Reflection,
Refraction, and Displacement, in that order.
Note: The sub-material and sub-map buttons for
most materials and maps have check boxes beside
each button. These turn that branch of the material
or map off or on. For example, in the Top/Bottom
material, the Top Material and Bottom Material
buttons each have check bo x es. Similarly, the
Checker map has two map buttons, one for each
color. Each button has check box beside it that lets
you turn off that color’s map.
