This daemon attracts particles towards its centre – negative values create a repulsion. Attraction forces become stronger near the centre and particles experience greater acceleration.
RealFlow Scene
In RealFlow | Maya it is possible to use multiple "Scene" trees in the same project. To link a daemon to a scene tree right-click on the field, choose "Set Scene", and select an item from the appearing list.
Linked Domains
All fluid, rigid, and elastic containers inside the field will be affected by the daemon. If there is only one container in the scene it will be linked automatically. Otherwise the connection has to be 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 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.
Internal force
This value determines the strength of the attraction (positive) or repulsion (negative) force.
Internal radius
If “Attenuated” is enabled this option becomes editable. The viewport gizmo's light blue circle indicates the radius where the force begins to decrease.
External force
If “Attenuated” is enabled this option becomes editable. It is the attractor’s strength in the outer area, defined by “External radius”.
External radius
If “Attenuated” is enabled this option becomes editable. The viewport gizmo's light blue circle indicates the radius where the decrease of the force ends.
Attenuated
This option unlocks three fields to specify the details for the force’s decease with growing distance from the centre.
Attractor type
You can choose from three types:
- “Spherical” is the default type and is represented by a point in the centre of the daemon.
- “Axial” produces a force field along a line from up to down – this line is also shown in the viewport. If you want to change the direction of the axis you have to rotate the daemon.
- “Planetary” is represented by a sphere. The daemon simulates a planet’s force which extends from the centre to outer space. Use “Planet radius” to control the sphere's size.
Planet radius
Control the radius of the virtual planet. This option is only available with “Attractor type" set to “Planetary”. The daemon’s viewport symbol represents the adjusted radius through green circles.
Axial strength
This is the vortex strength along the axial direction and can only be used with"Attractor type" set to “Axial”.
