Overview

The Marble texture map can be used to generate a procedural marble texture. It uses two colors that can also have texture maps assigned to them.

Parameters


 



Color Base – Specifies the main color of the marble. All parameters in this section can have a texture map assigned to their channel, as long as the checkbox is enabled. 

Color Vein – Specifies the color of the marble's veins

Vein Width – Controls the thickness of the marble veins.

Diffusion – Controls the amount of blur applied to the veins.

Contrast – Controls the contrast.

 

 

Noise Attributes


 

 

 

 

Amplitude  – Controls the amount of distortion in the marbles vein's. A value of 0 will make these a straight line. 

Ratio – Controls the amplitude ratio between two consecutive levels of the fractal noise. A value of 0 will make only the first noise level affect the result, and a value of 1 will make all noise levels affect the result with the same weight.

Ripples – Controls the distortion of the marble's veins non-uniformly.

Depth Min – Minimum level of the fractal noise.

Depth Max – Maximum level of the fractal noise.

 

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 specified here with the RGB color values of the texture. 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 for polygons with no valid UVs. In case the map is not tiles, the default color will be used outside the texture borders.

Use 3D Mapping – Enables or disables 3D mapping for the procedural texture. Note that his mode is not supported yet by the Hybrid (CUDA) engine.

 

Multipliers


 

 

 

Mode – Specifies the multiplication mode of the colors. 

Multiplier – 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. 
Blend Amount  Takes each pixel from the top layer if present. Otherwise the bottom layer is used.

Color Base – Controls the intensity of the marble Base Color.

Color Vein – Controls the intensity of the marble Vein Color.
