The translucency controls are available for the
Translucent shader (page 2–1326) .
Wa rn in g : Do not use shadow maps with the translucent
shader. Shadow maps result in artifacts at the edge of
translucent objects.
Procedure
To ma k e a mater ial tra nslucent:
•Increasethe HSV Va lue (V) (p age 3–1095) of
the Translucent Color.
As the Value increases, the material becomes
more translucent. The Hue of the Translucent
Color tints the light that is scattered within the
mater ial.
Translucent materials render more realistically

Shader Basic Parameters (page 2–1310) .The
translucent effect does not appear in shaded
viewports.
Example of translucency
Interfa ce
Translu cent Clr (Color)—Specifies a translucency
color. This is the color of light that is scattered
within the material. It does not need to be the same
as the filter color , which is light transmitted by
the material. The two color values are multiplied.
Click the color swatch to change the translucent
color. Click the button to assign a map to the
translucent color component.
Filter Color—Specifies a filter color (page 3–1033)
that is multiplied by the translucent color. Click
the color swatch to change the filter color. Click
the button to assign a map to the filter color
component.
The filter, or transmissive color, is the
color transmitted through transparent or
semi-transparent materials such as glass. You
can use the filter color with volumetric lig hting
to create effects such as colored light through a
stained-glass window.
Ray-traced shadows (page
3–1094)
cast by transparent objects are tinte d with
the filter color.
Opacit y —Sets the opacity/transparency (page
2–1330)
of th e material as a percentage. The effect
