This is a basic matte material with no specular, though it is simple to add. There are options for color map to be used as the surface color. It a good material for any soft powdery, non-reflective surface, such as clay, chalk, dirt, blackboards, matte paint, etc.
Parameters ¶
Surface ¶
Ambient Intensity
A multiplier for the 
ambient contribution
to the material. The ambient lighting model looks only at the ambient lights in the scene. If there are no ambient lights, this slider will have no affect.
Diffuse Intensity
A multiplier for the diffuse contribution to the material. This material uses the Oren-Nayer diffuse calculation. This is a more sophisticated diffuse calculation than Lambert’s.
Diffuse Roughness
This is an exponent for Oren-Nayer diffuse. It controls the size or spread of the diffuse contribution.
Use Base Color
If this box is not checked, the Base Color is ignored. Defaults to on. If Use Base Color, Use Point Color and Use Color Map are all off, the surface color will be white.
Base Color
This is the main surface color for the material. Defaults to white.
Use Point Color
If this box is checked and the point color, (Cd), is defined,
then Cd is multiplied with the Base Color. Defaults to on.
If Use Base Color, Use Point Color and Use Color Map
are all off, the surface color will be white.
Opacity
The opacity color for this material.
Use Point Alpha
If set, the Alpha attributes will be multiplied into the final Opacity. If no Alpha Attribute exists, Opacity is unaffected.
Color Map ¶
Use Color Map
If this box is checked the Base Color is multiplied by the specified texture map. Defaults to off. If Use Base Color, Use Point Color and Use Color Map are all off, the surface color will be white.
Base Color Map
This the name of the texture file. The icon to the right opens a file browser.
Color Map Wrap
Determines what the texture looks like when the texture coordinates are larger or less than 0 to 1. The options are:
-
Repeat means the texture will repeat (tile).
-
Streak means the texture color at the edges is clamped and streaks outside the map.
-
Decal sets the color outside the texture map to the Border Color. See
texture for more information.
Color Map Filter Type
Type of anti-aliasing filter used.
See texture for more information.
Color Map Filter Width
Filter Width is the number of pixels, in both u and v directions, to use in filtering.
Color Map Border Color
The color used outside the map if Decal Wrap is selected.
