The First Specular Layer and Second Specular
Layer groups have identical controls, which can
have different settings.
Co lor—Controls the specular color (page 3–1014)
of this highlight. The specular color is the color of
the high light on a shiny surface.
Leve l—Affects t he intensity of this specular
high light. As you increase the value, the highlight
grows brighter. Default: First layer=5, Second
layer=0.

specular level component. See Specular Level
Mapping (page 2–1501).Thisbuttonisashortcut:
you can also assign specular level mapping in the
Maps rollout (page 2–1474).
Glossiness—Affects the size of this specular
high light. As you increase the value, the highlight
gets smaller a nd the material appears shinier.
Default=25.
Clickthemapbuttontoassignamaptothe
glossiness component. See Glossiness Mapping
(page 2–1502). This button is a shortcut: you can
also assign specular level mapping in the Maps
rollout (page 2–1474).
Anisotropy—Controls the anisotropy, or shape, of
this high light. At 0, the h ighlight is round. At 100,
the h ighlight is extremely nar row. One axis of the
Highlight g raph changes to show changes in this
parameter. Default=0.
Orientation—Changes the orientation of this
highlight. The sample slot shows changes in
orientation. This is a value in degrees that can
range from 0 to 9,999. Default=0.
Highlight graph—These two intersecting cur ves

Glossiness, and Anisotropy. As you decrease
Glossiness, the curves g row wider; as you increase
Specular Level, the curves grow taller . As you
adjust Anisotropy, the white curv e changes to
show how wide or narrow the highlight is.

Like the Blinn shader, the Translucent shader has
circular highlights.
Procedures
To increa se or decrease the s trengt h of a hi ghlight:
• Change the value of Specular Level.
The intensity of the Highlight curve and the
highlight in the preview change. At 0% specular
level, there is no highlight. At values greater
than 100%, the curve is overloaded: it grows
wider, and a wider area is at the maximum
highlight intensity. At 100% specular level,
the cur ve is at its maximum height with no
overloading.

blending between the specular and diffuse color
regions of the material. The steeper the curve,
