Mapping metalness
Top: No mapping
Bottom: Map ping metalness with noise map
Yo u c a n s e l e c t a b i t m a p f i l e o r procedural map
(page 3–1091)
to control the Metalness par ameter.
White pixels in the map increase metalness. Black
pixels reduce metalness to 0. Intermediate va lues
adjust metalness accordingly.
The metalness parameter is available with the
Strauss shader (page 2–1324) .
Reducing the Amount of the metalness map
reduces the map’s effect, and increases the effect
of the Metalness value on the Basic Parameters
rollout. When the Amount is 0 percent, the map
isn’t used at all.
Procedure
To map the metalness value:
1.
Click the Map button for Metalness.
The
Material/Map Browser (page 2–1291) is
displayed.
2. Choose from the list of map types, and then
click OK.

Bump Mapping
Material Editor > Standard material > Maps rollout >
Bump button
An object with two different bump maps.
Yo u c a n s e l e c t a b i t m a p f i l e o r procedural map
(page 3–1091)
to use for bump mapping. Bump
mapping makes an object appear to have a bumpy
or irregular surface. When you render an object
with a bump-mapped material, lighter (whiter)
areas of the map appear to be raised, and darker
(blacker) areas appear to be low.
Note: The effect of a bump map is not previewed
in viewports. You must render the scene to see the
bump effect.
