Description

This node generates noise as a float type.



Properties

  • Noise Type : Choose between Perlin or White noise.
    Default : Perlin Noise

Perlin Noise properties

Perlin noise has a number of properties that can be set to fine-tune the noise to get different results : from high frequency, volatile noise to slow and smooth noise with or without sudden variations.

  • Minimum : Set the minimum threshold.
    Default : 0.0
  • Maximum : Set the maximum threshold.
    Default : 1.0
  • Frequency : Set the frequency. A higher frequency will produce a jittery noise similar to white noise.
    Default : 0.2
  • Octaves : Set the number of octaves, inducing sudden variations in the noise. A higher number will produce a more jittery noise with less amplitude.
    Default : 1
  • Octaves Weight : Sets the influence of the Octave number on the noise. A higher number will produce a more jittery noise with less amplitude.
    Default : 0.5
  • Periodic mode : If set, will force the noise to be identical over a period of time and repeat itself indefinitely.
    Default : OFF
  • Period : Sets the period (in seconds).
    Default : 0.0
    • This option is only visible if Periodic mode is ON
  • Seed : Change the seed being used for the random number generator.
    Default : 0

White Noise properties

White noise has a high frequency that cannot be changed and will always produce a very volatile noise.

  • Minimum : Set the minimum threshold.
    Default : 0.0
  • Maximum : Set the maximum threshold.
    Default : 1.0
  • Seed : Change the seed being used for the random number generator.
    Default : 0
