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

 

Overview

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

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.

Noise
Perlin
Inflected Perlin
Marble(with Perlin)

Amplitude – Controls the range of the Noise.

Frequency – Controls the the amount of Noise generated. Higher values create smaller, finer noise.

Inflection – Enables and disables the inflection effect.

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 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.

 

 

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

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