| Solid |
Switches between two-sided verses and one-sided properties. |
| Color |
Sets the color of the appearance in diffuse white light. |
| IOR (Index of Refraction) |
Controls how appearances with transparency bend light passing through them. It indirectly affects reflectivity. When using a surface without thickness, the IOR affects the reflectivity of the surface, but the light passing through it will not refract. On a surface with thickness, this appearance causes light to refract as it passes through the Solid object. |
| Color Density |
Determines the density of the color on the simulated surface, compared to solid glass in reality. Color Density affects the color saturation (tint) of glass with the Solid option enabled. The thicker the glass, the greater tint possible. |
| Roughness |
Controls the highlight size in reflected light. The rougher the appearance, the more it diffuses the highlight (the larger and less focused the highlight becomes), such as with frosted glass. |
