rollout
Attenuation settings cause distant objects to be dimmer.
The Intensity/Color/Attenuation rollout allows you to set the color and
intensity of your light. You can also define the attenuation of your light.
Attenuation on page 7915 is the effect of light diminishing over distance. In 3ds
Max, you can set attenuation values explicitly. The effects can vary from
real-world lights, giving you more direct control over how lights fade in or
fade out.
NOTE With no attenuation, an object can paradoxically appear to grow brighter
as it moves away from the light source. This is because the angle of incidence
more closely approaches 0 degrees for more of the object's faces.
Two sets of values control attenuation for objects. The Far attenuation value
sets the distance at which the light drops off to zero. The Near attenuation
value sets the distance at which the light "fades in." Both these controls are
turned on and off by a toggle called Use.
When Use is set for far attenuation, the light at its source uses the value
specified by its color and multiplier controls. It remains at this value from the
