The Checker texture map can be set to any color and generates a procedural checkerboard texture.

This section describes the input sockets of the node. Some sockets have dedicated parameters, which are further described below, and some sockets are just inputs.

Mapping – Allows a UVW Mapping or a UVW Randomizer node to be connected to determine the mapping of the ramp.

White Color (input socket) – Allows a color texture to be used as the White Color.

Black Color (input socket) – Allows a color texture to be used as the Black Color.

Contrast (input socket) – Allows an integer-outputting node to control the Contrast parameter.

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 – Controls the contrast between White Color and Black color, where 0 means no contrast and 1 results in maximum contrast.

Color Mult–  Corrects the color of the texture by multiplying 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.

Placement – Select how to place the texture. 

Whole Texture is Valid – Uses the full valid portion of the texture.
Crop – Allows the user to specify a section of the texture using the parameters below. 
Place – Allows the user to specify a section of the texture and how to place it using the parameters below.

Tile U – Enables horizontal tiling.

U – U coordinate of the texture sector. 

Width – Determines the width of the texture sector.

Tile V – Enables vertical tiling.

V – V coordinate of the texture sector.  

Height – Determines the height of the texture sector.

Jitter – Specifies a randomization value for the UV placement.

UV Noise On – Enables UV noise.  

Animate UV noise – If enabled, the noise is animated. Use the UV noise phase to animate the noise.

UV Noise Amount – Specifies the UV noise amount. 

UV Noise Levels – Specifies the UV noise iterations. 

UV Noise Size – Specifies the UV noise size.  

UV Noise Phase – Specifies the UV noise phase.
