Basic Parameters rollout

Upper left: No highlights

Upper right: Single highlight

Lower middle: Multiple highlights from the multi-layer

shader

The Multi-Layer shader is similar to the

Anisotropic shader (page 2–1321)

,butithasaset

of two specular highlig ht controls. The highlights

are layered, letting you create complex highlights

that are good for highly polished surfaces, special

effects, a nd so on.

Highlights in the Multi-Layer shader can be

anisotropic. Anisotropy measures the difference

between sizes of the highlight as seen from two

perpendicular directions. When anisotropy is

0, there is no difference at al l. The highlight is

circular, as in Blinn or Phong shading. When

anisotropy is 100, the d ifference is at its maximum.

In one direction the highlig ht is very sharp; in the

other direction it is controlled solely by Glossiness.
