You can use a bitmap file or procedural map to control the Metalness material component. White pixels in the map increase metalness. Black pixels reduce metalness to 0. Intermediate values adjust metalness accordingly.
Click the Material Editor icon on the Main toolbar or press M. Click and hold the icon to show the flyout.

Using a Metalness map:
Top: No map
Bottom: Using a Noise map as the Metalness map
The metalness parameter is available with the Strauss shader.
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.
Procedures
To use a Metalness map:
- Click the map button for Metalness.
3ds Max opens the Material/Map Browser.
- Choose from the list of map types, and then click OK.
(If you choose Bitmap as the map type, 3ds Max opens a file dialog that lets you choose the image file.)
- Use the map controls to set up the map.
Alternatively, you can use the
Slate Material Editor to
wire a map node to the Metalness component.
