Fractal noise, also called Pink noise is a signal with a frequency spectrum such that the power per frequency interval is inversely proportional to the frequency of the signal. Thus, each octave interval (halving or doubling the frequency) carries an equal amount of noise energy.

There are four types of noise presets to choose from :

Smooth Turbulent Warp Cellular



  • Clock : Animates the noise over time. To create animated noise connect a Graph Time node to this input and toggle your Graph to play.
    Default : 0.0
  • Speed : Sets the speed for the noise movement over time. This property will have no visible impact unless the Clock property is animated (see above).
    Default : 5.0
  • Complexity : Sets the number of iterations for the noise production. Lower values give less detailed noise. Values higher than 6 will consume more ressources for very little visible gain.
    Default : 6
  • Offset : Offsets the noise along the X and Y axes.
    Default : (WIDTH ; HEIGHT)
  • Sub Offset : A second offset for the noise along the X and Y axes.
    Default : (WIDTH ; HEIGHT)
  • Rotation : Set a rotation on the noise.
    Default : 0.0
  • Scale : Set a scale for the noise. Lower values give smaller noise (e.g. zoom out). Higher values give larger noise (e.g. zoom in).
    Default : (1.0 ; 1.0)
  • Brightness : Standard Brightness control.
    Default : 0.0
  • Contrast : Standard Contrast control.
    Default : 1.0
  • Color 1 : Set the first color for the noise.
    Default : White : 255 / 255 / 255 / 255
  • Color 2 : Set the second color for the noise.
    Default : Black : 0 / 0 / 0 / 255
  • Seed : Sets the seed for the randomness.
    Default : 12345.123


  • Type : Choose the noise type. Choices are : Smooth, Turbulent, Warp, Cellular
    Default : Smooth
  • Interpolation : Choose the interpolation type for the data between two frames. Choices are : Linear, Cubic, Quintic, Block
    Default : Linear


Name Type Description
Clock Float Animates the noise over time
Speed Float Changes the speed of the noise
Complexity Float Changes the number of iterations for the noise production
Offset Vector 2D Sets and offset for the noise along the X/Y axes
Sub Offset Vector 2D Sets another offset for the noise along the X/Y axes
Rotation Float Rotates the noise
Scale Vector 2D Changes the scale for the noise
Brightness Float Standard brightness input
Contrast Float Standard contrast input
Color 1 Color Input for the first color
Color 2 Color Input for the second color
Seed Float Change the seed for the randomness


Name Type Description
Image Image The image output of the noise


In this example :
  • Clock : Animated with the Graph Time
  • Speed : 3.0
  • Complexity : 6.0
  • Brightness : -0.1
  • Contrast : 1.25
  • Type : Smooth
  • Interpolation : Linear
    All other properties were left to default values.
