Lightscape Material 1413
Color B leed—
Increases or decreases the saturat ion
of reflected color. Range=0.0 to 1.0. Default=1.0.
Color Bleed increases or decreases the saturation of
reflected color.
Transmittance Scale—Increases or decreases
the amount of energ y the material transmits.
Range=0.1 to 5.0. Default=1.0.
Transmi ttance Scale increasesordecreasestheenergyof
transmitted rays.
Note: This parameter affects only radiosity. It has
no effect on light tracing.
Special Effec ts group
These parameters relate to specific components in
thebasematerial.
Luminance Scal e (cd/m^2)—When greater than
zero, scales the
self-illumination component (p age
2–1328)
ofthebasematerial.Usethisparameter
to have self-illuminating objects contribute energy
to the radiosity or light-traced solution. Cannot be
less than zero. Default=0.0.
Typically, a value of 500 or more will give good
results.
Indirect Light Bump Scale—Scales the effect of the
base m aterial’s
bump mapping (page 2–1347)
in areas lit by indirect light. When this value is
zero, no bump mapping is done for indirect light.
Increasing Indirect Lig ht Bump Scale increases the
bump effect under indirect lig hting. This value
does not affect the Bump amount in areas where
the base material is lit directly. Cannot be less than
zero. Default=1.0.
Tip: This p ar ameter is useful because indirect
bumpmappingissimulatedandnotalways
accurate. Indirect Light Bump Scale lets you adjust
the effect by hand.

existing Lightscape radiosity meshes.
Note: This material is for use with Lig htscape. It
is
not meant for use with the advanced lighting
solution in 3ds Max. For adjusting a material’s
radiosity properties in 3ds Max, use the
Advanced
Lighting Override material (page 2–1410)
.

not suppo rt the Lightscape material.
