You can define the following properties for glass materials on the Appearances tab in the Material Editor panel of the Material Browser dialog.
| Property | Description |
|---|---|
| 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 Specifying a Render Appearance Color. |
| 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%. |
| 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. |
| Relief Pattern | Relief pattern to use on the finished surface. A relief pattern defines raised and lowered areas based on dark and light areas of an image file. To define a custom relief pattern, select Custom. See Specifying an Image File for a Render Appearance. |
