This page provides information on the V-Ray Checker Texture.
Overview
The Checker texture map can be set to any color and generates a procedural checkerboard texture.
Any texture can be replaced via the Replace With New Texture (
) button, which activates when you select the texture to be replaced. If the texture is an instance, all copies are changed as well.
Parameters
Color A – Specifies a color or texture for what would usually be the white squares on the checkerboard.
Color B – Specifies a color or texture for what would usually be the black squares on the checkerboard.
Color Manipulation
Invert Texture – Inverts the RGB texture values.
Alpha from Intensity – Uses the texture RGB intensity/ luminance as alpha channel.
Color Gain – Corrects the color of the texture by multiplying the the RGB color values in the texture with the RGB color values specified here. When a texture is selected, it overrides the color as long as the texture checkbox is enabled.
Color Offset – Corrects the color of the texture by adding the RGB color values specified here to the RGB color values of the texture. When a texture is selected, it overrides the color as long as the texture checkbox is enabled.
Default 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.
Multipliers
Mode – Specifies the multiplication mode of the colors.
Multiply – The color used for blending is black.
Blend Amount– The color used for blending is the one specified in the color slot.
Color A – Specifies blends between a color and a texture, if specified.
Color B – Specifies blends between a color and a texture, if specified.
Texture Placement
Type – Controls how the texture is positioned on the geometry.
2D (UV Channel) – The texture uses the object UV coordinates.
Environment – This mode is applicable if the map is connected to an Environment slot or a Dome light.
Mapping Source – The texture uses an external UV placement source.
2D (UV Channel)
UV Channel/Set – Specifies the index of the mapping channel data to use. A value of 1 takes the first available channel.
Repeat U/V – Determines how many times the texture is repeated in the 0 to 1 UV square.
Lock U/V Repeat – Locks the U/V Repeat.
Offset U/V – Controls the texture offset in the U and V direction.
Rotate – Rotates the texture (in degrees).
Tile U/V – Tiles the texture in the U and V direction. If the option is disabled, the Default texture color is used outside the 0 to 1 UV square. Default color is found in Parameters > Color Manipulation.
Mirror U/V – Mirrors the texture in the U and V direction separately. The option cuts the texture in the half flipping one side vertically or horizontally. This can be used to avoid seams in-between non-tileable repeated textures.
Environment
Mapping – Specifies the type and shape of the texture.
Angular
Cubic
Spherical
Mirror Ball
Screen
Rotate H – Rotates the environment sphere horizontally.
Flip H – Flips the environment sphere horizontally.
Rotate V – Rotates the environment sphere vertically.
Flip V – Flips the environment sphere vertically. This option is active only in Spherical Mapping.
Ground – Enables ground projection of the texture.
Position X/Y/Z – Offsets the ground projection along the X/Y/Z axis.
Radius – Specifies a projection radius. Can be used to control the scale of the projection.
2d Transformation – see 2D (UV channel) parameters.
Mapping Source
UV Placement Source – External UV placement source to be used for the texture placement.
