This daemon is used to simulate noisy wind. Like many other daemons, wind forces can be bounded to limit them. An arrow indicates wind direction.

RealFlow Scene

In RealFlow | Cinema 4D it is possible to use multiple "Scene" trees in the same project. To link a daemon to a different scene tree drag the appropriate "Scene" node to this field.

Linked

All fluid, rigid, and elastic containers inside the drag-and-drop field will be affected by the daemon. The first fluid If there is only one container in the scene is it will be linked automatically, others have . Otherwise the connection has to be attached established manually.

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 particles 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 wind force's scaling factor.

Noise Strength

This value is the scaling factor for a random force that will be added to “Strength”. Both “Strength” and “Noise Strength” are defined independently, but added to compute the final force:

• If you increase “Strength” in conjunction with noise then you have to increase “Noise Strength” accordingly, because otherwise the noise pattern will change.
• With “Strength“ set to 0 and a “Noise Strength” greater than 0 you will get the same behaviour as with the “Noise Field” daemon.

Noise 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.

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

“Yes” creates a conical shape – its dimensions are displayed in the viewport. The gizmo's size is adjusted with “Radius 1| 2” and “Height”. You can use the parameters from the “Objects” tab or Cinema 4D's scale tools for resizing the daemon. 

Radius 1

This is the radius of the bounding cone at the daemon's pivot point.

Radius 2

This is the radius of the bounding cone at the daemon gizmo's height.

Height

Change the viewport gizmo's height with this setting.
