Shadow
Makes the light cast shadows.
Off Turns off display and calculation of shadows for the light. Turning shadows
off increases performance.
Sharp Displays shadows with sharp edges. Use this option to increase
performance.
Soft Mapped Displays realistic shadows with soft edges.
Map Size Specifies the amount of memory that should be used to calculate
the shadow map.
Softness Specifies the softness that should be used to calculate the shadow
map.
Soft Sampled Displays realistic shadows with softer shadows (penumbra)
based on extended light sources.
Specify the shape of the shadow by entering s and then the dimensions of the
shape. (For example, the radius of the sphere or the length and width of a
rectangle.)
Specify the sample size by entering a.
Specify the visibility of the shape by for the shadow by entering v.
Attenuation
Enter an option to change [attenuation Type/Use limits/attenuation start
Limit/attenuation End limit/eXit]<eXit>:
Attenuation Type Controls how light diminishes over distance. The farther
away an object is from a spotlight, the darker the object appears. Attenuation
is also known as decay.
■ None. Sets no attenuation. Objects far from the spotlight are as bright as
objects close to the light.
■ Inverse Linear. Sets attenuation to be the inverse of the linear distance
from the light. For example, at a distance of 2 units, light is half as strong
as at the spotlight; at a distance of 4 units, light is one quarter as strong.
The default value for inverse linear is half the maximum intensity.
■ Inverse Squared. Sets attenuation to be the inverse of the square of the
distance from the light. For example, at a distance of 2 units, light is one
quarter as strong as at the spotlight; at a distance of 4 units, light is one
sixteenth as strong.
Use Limits Specifies whether to use limits or not.
