Granite

The Granite texture map generates a procedural Granite texture. It uses four colors that can be changed or assigned to texture maps.

Color Base – Specifies the color that fills in the area surrounding the spots. A texture map can be used for all parameters in this section, as long as the checkbox is enabled. 

Color A – Specifies the first color of the spots. 

Color B – Specifies the second color of the spots.

Color C – Specifies the third color of the spots. 

Cell Size – Controls how large or small the cells are. For more information, please see the Cell Size example below.

Density – Controls how closely packed the spots are. For more information, please see the Density example below.

Mix Ratio – Controls the prominence of each color relative to the others. For more information, please see the Mix Ratio example below.

Threshold – Controls the transition between the filler color and Color 1, Color 2 and Color 3. 

Spottiness – Controls how circular the spots are. Lower values make the spots more circular, and higher values make them less circular. 

Randomness – Varies the distribution of the spots on the granite. Lower values show more spots, higher values also make them more sparse. For more information, please see the Randomness example below.

Creases – Enables or disables crease patterns.

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 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 in 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.

Mode – Specifies the multiplication mode of the colors. 

Multiply – Multiplies the RGB numbers for each pixel of the top layer with the RGB number of the corresponding pixel from the bottom layer. The result is a darker picture. The color used for blending is black.
Blend Amount–  Takes each pixel from the top layer if present. Otherwise the bottom layer is used. The color used for blending is the one specified in the color slot.

Color Base – Blends between the color base and a texture, if specified. 

Color A – Blends between the first color and a texture, if specified. 

Color B –  Blends between the second color and a texture, if specified.

Color C – Blends between the third color and a texture, if specified. 

Example: Mix Ratio

These examples use a Density of 1 and a Cell Size of 0.75.

Example: Spottiness

These examples use a Density of 1, a Cell Size of 0.75 and a Mix Ratio of 0.5

Example: Randomness

These examples use a Density of 1, a Cell Size of 0.75 and a Mix Ratio of 0.5

Example: Cell Size

Type – Controls how the texture is positioned on the geometry.

2D (UV Channel) – The texture uses the object UV coordinates.
3D (Object Space) – Places the texture based on the local object coordinates independent of the object UVs.
3D (World Space) – Places the texture based on the world coordinates independent of the object UVs
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. 

3D (Object Space)

Repeat X/Y/Z – Determines how many times the texture is repeated along the X/Y/Z axis.

Lock U/V Repeat – Locks the X/Y/Z repeat.

Offset X/Y/Z – Controls the texture offset in the X/Y/Z direction.

Rotate X/Y/Z – Rotates the texture around the X/Y/Z axis.

3D (World Space)

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.
