Noise Falloff


This node constructs a position-based falloff where the falloff value of the element is the target noise evaluated at the element’s position. The node supports many types of noises including Perlin, Simplex, Value, Cubic, Cellcular (Voronoi), and White Noise. The node also supports fractal versions of the noises as well as distorted versions.


  • Seed - A seed value.
  • Amplitude - The maximum value of the noise.
  • Frequency - The frequency of the noise.
  • Axis Scale - A vector controlling the frequency of the noise along each axis individually.
  • Offset - An offset that is added to the input elements before evaluation. The offset can be used as a continues seed or for animating the noise.
  • Octaves - The number of octaves to be added. Higher values corresponds to more detailed noises but increases the execution time.
  • Jitter - The amount of randomness in the cellular noise. A lower value corresponds to a more uniform pattern.


  • Falloff - The output falloff.

Advanced Node Settings

  • Fractal Type - The method used to add the octaves of the noise.
  • Pertube Type - The method used to distort the noises.
  • Distance - The distance metric used to compute the cellular noise.
