Spread operator

The Spread operator allows you to directly move particles in various directions, by adjusting their position instead of applying forces.

Position Offsets

  • X/Y/Z: allows you to move particles along a world-aligned axis by a precise value.

Random Spread

  • X/Y/Z: the overall distance to move particles, in random directions.

  • ± X/Y/Z: controls the amount of variation to apply to the initial X/Y/Z distances.

Noise Spread

The noise settings allow you to offset the way in which particle positions are moved.

  • Strength: the strength of the noise.

  • Frequency: the frequency of the noise. Increasing this value will evolve the noise pattern over time.

  • Scale: the scale of the noise.

  • Roughness: the roughness of the noise.

  • Iterations: the number of iterations to use to calculate the noise.


  • Affect velocity direction: controls whether the direction between a particle’s old position and its new position will affect the direction of its velocity vector.


  • Seed: the seed value for all varied parameters.

  • Seed by time: the seed value will be incremented with the current time in ticks.
