Transparent materials render more realistically

Shader Basic Parameters (page 2–1310) .
To increase or decrease the size a nd intensity of
highlights:
• Change t he Glossiness value.
The width of the Highlight curve and the
high lights in the preview change. At 0%
gloss iness, the curve is at its maximum width.
At 100% glossiness, the curve is extremely
narrow.
Increasing Glossiness also dims the diffuse
color.
To mak e the material appear more metallic:
1.
Increase the Glossiness value.
The meta l lic effect requires visible hig hlights.
2. Increase the value of Metalness.
Highlights become more focused, and the
(diffuse) color component is dimmed.
Inter face
Co lor—Controls the color of the material. This
corresponds to the
diffuse color (page 3–1023)
you specify for other kinds of shaders. With the
Strauss shader, you control o nly this color. The
shader calculates the ambient and specular color
components.
Click the map button to assign a map to the color
component. See
Diffuse Mapping (page 2–1339) .
This button is a s hortcut: you can also assign color
mapping in the
Maps (page 2–1315) rollout.
Glossines s—Affe cts the size and intensity of the
specular highlight. As you increase the value, the
highlight gets smaller and the material appears
shinier. D efault=25.
Glossiness also controls the strength of reflection
maps assigned to a Strauss mater ia l.

rollout.
Metalness—Changes the metallic appearance of a
material.IncreasingtheMetalnessvalueincreases
the metallic appearance, with glancing as well as
primary highlights. Because a metallic appearance
principally depends on highlights, the Metalness
value has little effect unless you also increase the
Glossiness value. Default=0.
Tip: When you create a metal material, make sure
the
backlight (page 2–1276) is on in the sample
slot.
Opacit y —Sets the opacity/transparency of the
material as a percentage. The effect is best
previewed against a
