This rollout contains controls for fine-tuning the effect of the Raytrace map.

Interface

Reflectivity/Opacity—These controls affect the intensity of the raytracer's results.

Spinner—Controls the amount of raytracing used by the material it is assigned to. Analogous to the Output Amount parameter in the Output rollout of the Bitmap map type.
Map button—Assigns a map that controls the amount of raytracing. You can vary the amount of raytracing used over the surface of the object.
Check box—Enables or disables the map.

Tint—With these controls, you can tint the colors returned by the raytracer. Tinting applies only to reflected colors; it doesn't affect the material's diffuse component.

Check box—Turns basic tinting on or off. Default=off.
Color swatch—Assigns a tint color for reflections. Default=white.
Amount spinner—Sets the amount of tinting used. Default=1.0.
Map button—Assigns a map to use for tinting. You can vary the tint colors over the surface of the object.
Check box—Enables or disables the map.

Bump Map Effect—Controls the effect of a bump map on rays that the surface reflects and refracts. For example, you might want to make a glass object highly bumpy, but reduce the bump effect on refracted parts of the scene.

Bump Map Effect equals 1.0.

The refraction of tiles behind the glass is distorted by the bump map.

Bump Map Effect equals 0.0.

The refraction of tiles behind the glass is not distorted.

Bump Map Effect is active only when raytracing is enabled.
