Creates or modifies a material that simulates granite. The dialog box provides
attribute options that are specific to the GRANITE material type. All other
options in this dialog box are the same ones found in the New or Modify
Standard Material Dialog Box.
Granite Attributes
Specifies the material attribute to change. The Value and Color settings affect
the selected attribute. If a setting does not apply to an attribute, it is not
available while that attribute is selected.
Bump Map
Makes the Bitmap Blend area available to specify the file name of a bump
map.
First, Second, Third, Fourth Color
Adjusts the four colors that can be present. The options in the Color area
are the same as for standard materials, except that Lock is not present. By
ACI is available only when Reflection is selected. To use fewer than four
colors, set a color value equal to one of the other colors, or set its value to
zero. Value specifies the relative amount of each color in the granite pattern.
Reflection
Adjusts the material’s reflective (highlight or specular) color. You can adjust
the color using Value and the options in the Color area. The color swatch
displays the color.
