The Point Force operator allows you to inject radial forces into a simulation, at particle locations.
Strength:: the strength of each point force.
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.
Duration: the duration, in frames, each point force will be active.
Decay: the amount of decay to apply to forces, each time step.
Decay will decrease force strength over time.
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.
