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.

 

 

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 funcitions. 

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 for polygons with no valid UVs. In case the map is not tiles, the default color will be used outside the texture borders. When a texture is selected, it overrides the color as long as the texture checkbox is enabled. 

 


Use 3D Mapping – Enables or disables 3D mapping for the procedural texture. Note that this mode is not supported yet by the Hybrid (CUDA) engine. When this option is enabled, all Texture Placement parameters are ignored.

 

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 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.
