To increa se or decrease the str ength of a highli ght:
• ChangethevalueofSpecularLevel.
TheintensityoftheHighlightcurveandthe
highlight in the preview change. At 0% specular
level, there is no highlig ht. At values g reater
than 100%, the curve is overloaded: it grows
wider, and a wider area is at the maximum
highlig ht intensity. At 100% specular level,
the curve is at its maximum height with no
overloading.
TheshapeoftheHighlightcurveaffectsthe
blending between the specular and diffuse color
regions of the material. The steeper the curve,
the less blending there is and the sharper the
edge of the specular hi g h light.
To increase or decrease the size of a highlight:
• Change t he Glossiness value.
The width of the Highlight curve and the
highlight in the preview change. At 0%
gloss iness, the curve is at its maximum width.
At 100% glossiness, the curve is extremely
narrow.

Specular Level—Affects the intensity of the specular
high light. As you increase the value, the highlight
grows brighter. Default=0.
Click the map button next to the spinner to
assign a map to the specular level component.

.
Glossines s—Affe cts the size of the spe cular
highlight. As you increase the value, the highlight
gets smaller and the material appears shinier.
Default=10.

Ba ck side specular—When on, both sides of the
material receive a specular highlight. When off,
only the front side of the material receives a
highlight. Default=on.

Tip: When Backside Specular is turned off,
the front side is always the one that receives
a specular highlight. You can change this by
reversing the normals of surfaces that have the
translucent-shaded material.
