Parameters rollout
The Strauss shader is for modeling metallic
surfaces. It uses a simpler mo del and has a simpler
interface than the Metal shader (page 2–1481).
Sample of Strauss shading
Note: The Strauss shader’s Basic Parameters rollout
differs a great deal f rom the Basic Parameters
rollouts for other shaders, and is described in this
topic.

Pr ocedur es
To change the color of a Strauss material:
1.
Click the Color swatch.
The Color Selector (page 1–161) is displayed.
Right-clicking the color swatch also displays
the Color Selector.
2. In the Color Selector, change the values of the
color.
As you change color values, the color also
changes in the sample in the sample slot.
To reduce a materia l’s opaci ty:
• Change Opacit y to a v alue less than 100%.
The material b ecomes more transparent. An
object that is fully transparent (0% Opacity) is
nearly invisible except for the light it reflects
(the specular hig hlights).
To preview t r ansparency in the sample slots,
view the sample object against a background.
Click the checkered Background (page 2–1433)
button to t he right of the sample slots.
Transparent materials render more realistically
when you tur n on 2-Sided in the m aterial’s
Shader Basic Parameters (page 2–1466).
To increase or decrease the size a nd intensity of
highlights:
• Change the Glossiness value.
The width of the Highlight curve and t he
highlights in the preview change. At 0%
glossiness, the curve is at its max imum width.
At 100% glossiness, the curve is extremely
narrow.
Increasing Glossiness also dims the diffuse
color.
To mak e the material a ppear more metallic:
1.
Increase the Glossiness value.
The metallic effect requires visible high lights.
2. Increase the value of Metalness.
Highlights become more focused, and the
(diffuse) color component is dimmed.
