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

With “Force” it takes a little time to display the daemon's full influence and the result is a curved stream of particles. “Velocity” directly affects the particles from the very beginning without any delay or acceleration, and you will get a linear particle stream. “Velocity” is not available for rigid/soft bodies.

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.

Bounded

A bounded “Noise Field” is restricted to a sphere, which is displayed in the viewport around the node’s centre. You can also change the shape’s size with the "Scale" parameters of the → "Node" panel or the R key.
