This page provides information about the Checker texture in V-Ray for Blender.
Overview
The Checker texture map can be set to any color and generates a procedural checkerboard texture.
Input
White Color – Specifies a color or texture for what would usually be the white squares on the checkerboard.
Black Color – Specifies a color or texture for what would usually be the black squares on the checkerboard.
Contrast –
Output
Color Mult– Corrects the color of the texture by multiplying the the RGB color values in the texture with the RGB color values specified here.
Color Offset – Corrects the color of the texture by adding the RGB color values specified here to the RGB color values of the texture.
Invert – Inverts the RGB texture values.
Alpha Source – Specifies where the alpha channel is drawn from.
Bitmap Alpha – Alpha channel is drawn from the texture.
Color intensity/luminance – Alpha is generated from pixel intensity.
Force Opaque – Alpha channel is fully opaque.
Invert Alpha – When enabled, the resulting texture alpha is inverted as well.
Alpha Offset –
No UVs Color – Specifies a default color used for polygons with no valid UVs. In case the map is not tiled, specifies a default color that is used outside the texture square. When a texture is selected, it overrides the color as long as the texture checkbox is enabled.
