You can select a bitmap file or procedural map to control the Diffuse Level parameter. White pixels in the map leave the diffuse level unchanged. Black pixels reduce the diffuse level to 0. Intermediate values adjust the diffuse level accordingly.

The diffuse level parameter is available with the Anisotropic, Oren-Nayar-Blinn, and Multi-Level shaders.

Reducing the Amount of the diffuse level map reduces the map's effect, and increases the effect of the Diffuse Level value on the Basic Parameters rollout. When the Amount is 0 percent, the map isn't used at all.


To map the diffuse level value:

  1. Click the Map button for Diffuse Level.

    The Material/Map Browser is displayed.

  2. Choose from the list of map types, and then click OK.

    The Material Editor is now at the map level, and displays controls for the map parameters.

  3. Use the map controls to set up the map.
