You can define the following properties for glass materials on the of the Materials dialog. See also .
|Color (Transmittance)||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 .|
|Reflectance||Percentage of light striking the glass that bounces off rather than being absorbed or passing through (transmittance). Enter a value between 0% and 50%.|
|Index of Refraction||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 refraction) and 5 (most refraction).|
|Roughness||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 irregularities.|
|Bump Pattern||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, select Custom. See .|
