Daemons - Noise Field

The noise function gives you extra realism by adding a random force field. This daemon can be used to randomly disturb particles or objects, which is particularly useful for nebula-like effects and simulating air turbulences.

 

 

Affect

There are two options:

  • "Force" accelerates the particles and they become faster and faster as long as the force is acting on them. 
  • “Velocity” only works with particles and adds the daemon's "Strength" value to a particle's speed. The resulting peak velocity remains constant during the simulation.
    An example: Let's assume the daemon's "Strength" is 9.8 and the emitter's "Speed" value is 2.0. Here, a particle's velocity will be roughly 11.8 m/s.
Strength

This value is the scaling factor for a random force.

Space scale

Here the overall size or frequency of the noise in space is controlled. Be aware that high scale values lead to more noise.

Time scale

RealFlow's noise functions create a pattern that is repeated over time. With 0 the noise pattern remains constant during simulation. With higher settings, the noise pattern will change faster, but it will also be repeated in shorter cycles.
