Description Property
Relative height or depth of the specified bump pattern. Enter 0 to make the surface
flat. Enter higher decimal values (up to 1.0) to increase the depth of the surface irreg-
ularities. Amount
Glass Properties
You can define the following properties for glass materials on the Render Appearance tab of the Materials
dialog. See also Glass, glazing, and mirrors on page 477.
Description Property
Color of the glass. (Transmittance refers to the light that passes through the glass.)
Select a predefined glass color, or select Custom to specify a color. See
Specifying a
Render Appearance Color on page 476.
Color (Transmittance)
Percentage of light striking the glass that bounces off rather than being absorbed or
passing through (transmittance). Enter a value between 0% and 50%. Reflectance
Measurement of how much a ray of light bends when entering the glass. Select a
predefined index, or select Custom to specify an index number between 0 (no refrac-
tion) and 5 (most refraction). Index of Refraction
Relative amplitude of bumps in the surface of the glass. Enter 0 to make the surface
flat. Enter higher decimal values (up to 1.0) to increase the depth of the surface irreg-
ularities. Roughness
Bump pattern to use on the finished surface. A bump pattern defines raised and
lowered areas based on dark and light areas of an image file. To define a custom Bump Pattern
bump pattern, select Custom. See Specifying an Image File for a Render Appearance
on page 476.
Glazing Properties
You can define the following properties for glazing materials on the Render Appearance tab of the Materials
dialog. See also Glass, glazing, and mirrors on page 477.
Description Property
Color of the glazing. (Transmittance refers to the light that passes through the glazing.)
Select a predefined glazing color, or select Custom to specify a color. See
Specifying
a Render Appearance Color on page 476.
Color (Transmittance)
Percentage of light striking the glass that bounces off again (like a reflection) rather
than being absorbed or passing through (transmittance). Enter a value between 0%
and 50%. Reflectance
