Point Force operator

The Point Force operator allows you to inject radial forces into a simulation, at particle locations.


Point Force

  • Strength:: the strength of each point force.

  • Variation %: the per-particle percentage of variation to apply.
Noise

Allows you to add turbulence to the point forces.

  • Strength: the strength of the turbulent noise.

  • Frequency: the frequenrcy of the turbulent noise.

  • Scale: the scale of the turbulent noise


  • Relative to mass: the force applied to a particle will be relative to its mass.

  • Ignore source particle: the particle from which the force originated will not be affected by the force.

Force Timing

  • Duration: the duration, in frames, each point force will be active.

  • Variation %: the per-particle percentage of variation to apply.
  • Decay: the amount of decay to apply to forces, each time step.

Decay will decrease force strength over time.

Force Influence

  • Distance: particles within this distance will be fully affected.

  • Falloff: the effect on particles beyond the base distance, but within this falloff distance, will diminish according to the inverse-square law.

Variation %: the per-particle percentage of variation to apply.

Simulation Groups

  • Simulation groups: controls which particle simulation groups will be affected by the point forces.

Display

  • Show point forces: controls whether point forces will be visualized in the viewport, as spheres representing the size of their influence in the scene.

Uniqueness

  • Seed: the seed value for all varied parameters.
