"Vortex" creates a force field around the daemon's centre and along its vertical axis. Both forces can be adjusted independently. All scale settings of the bounded daemon have to be adjusted under the “Vortex” panel. The closer the particles are to the axis, the faster the rotational motion will be.
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 bodiesThere 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.
Rot strength
This is the strength of the rotational force around the daemon’s centre axis. “Rot strength” accepts positive (clockwise) and negative (counter-clockwise) values.

You can choose from three fall-off types: “Linear”, “Squared” and “Cubic”. The fastest attenuation is achieved with “Cubic”.
Bounded
With “Yes” the "Vortex" daemon is displayed with a stack of three rings around the axis. The radius ("Boundary") of these rings determines the zone of influence.
Boundary
Here the radius of the zone of influence is adjusted in metres.
Vortex type
“Classic” creates a homogeneous force field, where the fall-off obeys the adjusted “Attenuation”. With “Complex” the forces reach their peak strength at a given distance (= “Radius”) from the centre. This distance is displayed as a dashed circle line around the centre.
...
To use this setting,”Vortex type” must be set to “Complex”. “Radius” determines the distance from the vortex centre in metres where the forces reach their maximum.
Bounded
With “Yes” the "Vortex" daemon is displayed with a stack of three rings around the axis. The radius ("Boundary") of these rings determines the zone of influence.
Boundary
Here the radius of the zone of influence is adjusted in metres.
Bound Sup
This is the upper limit of the vortex.
