The reflection options provide advanced controls over the reflections on the coating layer. They can be used to achieve special effects and to optimize rendering times.
| • | Reflection Falloff – World space distance for length of reflection rays. At this distance reflection rays fall off to either the Reflection Falloff Color or to the environment color. If set to -1, reflection falloff is disabled. Any alteration to this value requires a retrace. |
| • | Falloff to Color – If enabled reflections will fade to Falloff Color. If it is not enabled, reflections will fade to the environment. |
| • | Falloff Color – Specifies the color of reflections that have exceeded the Reflection Falloff distance |
| • | Reflection Max Ray Depth – Material override for the global maximum ray depth of reflection rays, that is set in Shaderlight Exporter Options->Ray Depth. |
| • | Reflection Cutoff – If reflections from this material will contribute less than this value to the pixel color value in the final image, then Shaderlight will avoid tracing them, to render faster. |
| • | Number of Samples – The number of sample rays spawned by a glossy reflection. Low values will use less memory, and higher values will show more noise in the reflections. A suggested range is from 8 to 32. |
