Raytrace: Basic Material Extensions Rollout

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.
