This page provides information on the V-Ray Noise B Texture.

 

Overview

The Noise B texture map can be used to generate a procedural noise texture. It uses an intuitive set of parameters to control the noise appearance. The Size option changes the noise size/frequency and the Levels parameters can easily increase the contrast and sharpness of the effect.

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 – Controls the first of the two colors used by the Noise procedural. When a texture is selected, it overrides the color as long as the texture checkbox is enabled. 

Color B – Controls the second of the two colors used by the Noise procedural. When a texture is selected, it overrides the color as long as the texture checkbox is enabled. 

Type – Specifies the type of noise to be created through the Noise procedural.

Regular
Fractal
Turbulence

Size – Specifies the Noise size. 

Iterations – Specifies how much fractal energy is used for the Fractal and Turbulence noise functions. 

Phase – Controls the seed. Change the number to generate a new random pattern. 

Levels

Low – Specifies the low threshold. 

High – Specifies the high threshold.

Color Manipulation

Invert Texture – Inverts the RGB texture values.

Alptha 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 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 – 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 A – Controls the intensity of the first color. When a texture is selected, it overrides the color as long as the texture checkbox is enabled. 

Color B – Controls the intensity of the second color. When a texture is selected, it overrides the color as long as the texture checkbox is enabled.
