Reflectivity/Opacity—
These controls affect the
intensity of the rayt racer’s results.
•
Spinner —Controls the amount of raytracing
used by the material it is assigned to. Analogous

rollout of the
Bitmap map type (page 2–1441) .
•
Ma p button—Assignsamapthatcontrolsthe
amount of raytracing. You can vary the amount
of raytracing used over the surface of the object.
•
Che ck 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.
•
Che ck box—Tur ns basic t inting on or off.
Default=off.
•
Co lor swatch—Assigns a tint color for
reflections. Default=white.
•
Amount spinner —Sets the amount of tinting
used. Default=1.0.
•
Ma p button—Assigns a map to use for tinting.
You can vary the tint colors over the surface of
the object.
•
Che ck box—Enables or disables the map.
Bump Map Effect—Controls the effect of a bump
maponraysthatthesurfacereflectsandrefracts.
For example, you might w ant 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 refrac tion of tiles behind the glass is distorted by the
bump map.
Bump Map Effect equals 0.0.
The refraction o f tile s be h ind the glass is not distor te d.
Bump Map Effect is active only when raytracing
is enabled.
