Checkerboard

This is a basic material with checked color map.

This is a basic material with a checked color map used as the surface color. This material has a choice of specular functions and a map for the specular contribution.

Parameters

Surface

Ambient Intensity

A multiplier for the ambient contribution to the material. The ambient lighting model only looks at the ambient lights in the scene. If there are no ambient light, this slider will have no affect.

Lambert Intensity

A multiplier for the diffuse contribution to the material.

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.

Check Frequency

This is the number of times to tile (repeat) the map specified below.

Base Color Map

This the name of the texture file. It defaults to gBWCheck.rat. This is a 2 by 2 black and white checked map. 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 of anti-aliasing filter used. See texture for more information.

Color Map Width

Filter Width is the number of pixels, in both u and v directions, to use in filtering. See texture for more information.

Color Map Border

The color used outside the map if Decal Wrap is selected. See texture for more information.

Specular

Specular Intensity

A multiplier for the specular contribution to the material.

Specular Color

The specular highlight color, defaults to white.

U Roughness

This value controls the size or spread of the specular highlight. When Anisotropic is selected, this value controls the specular highlight only in the U direction.

V Roughness

When Anisotropic is selected, this value controls the specular highlight only in the V direction. It is ignored with any other specular function.

Sharpness

This value controls the sharpness of the edge of the specular highlight. It is used only if Glossy specular is selected.

Specular Type

A selector for the specular function. Anisotropic is used to get an elliptical highlight. Glossy is typically used for highly reflective materials to get a sharp edges highlight. See specular for more information.

Specular Map

Use Specular Map

If this box is checked, the specular color is multiplied by the color of the texture in Specular Map. Defaults to off.

Specular Map

This the name of the texture file. The icon to the right opens a file browser.

Spec 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.

Spec Map Filter

Type of anti-aliasing filter used. See texture for more information.

Spec Map Width

Filter Width is the number of pixels, in both u and v directions, to use in filtering. See texture for more information.

Spec Map Border

The color used outside the map if Decal Wrap is selected. See texture for more information.
