Specular Level—Affects the intensity of the
specular highlight. As you increase the value, the
high light grows brighter and the diffuse color
grows dimmer. Default=5.

Glossiness—Affects t he size of the specular

Specular Layer groups
Multi-layer high lights consist of two layers, each of
them anisotropic. The hig h lights are transparent
to each other. Where they overlap, the Mu lti-Layer
shader blends their colors.
Procedures
To increase or decr ease the size of a highlight
(specular) layer:
• Change the Glossiness value.
ThewidthoftheHighlightcurvesandthe
highlights in the preview change. At 0%
glossiness, the curves are at their m aximum
w idth. At 100% glossiness, both curves are
extremely narrow.
To increase or decrease the str ength of a highlight
(specular) layer:
• Change the value of Specular Level.
TheintensityoftheHighlightcurvesand
the hig hlights in the preview change. At 0%
specular level, there is no highlight. At 100%
specular level, the curves are at their maximum
height with no overloading. At values greater
than 100% , the curves are overloaded: they
grow wider, and a wider area is at the maximum
highlight intensity.
TheshapeoftheHighlightcurvesaffectsthe

regions of the material. The steeper the curve,
the less blending there is and the sharper the

To a djust the shape (ani sotropy ) of a highlight
(specular) layer:
• Change t he value of Anisotropy.
