This creates a Vortex field. See Work with vortex fields.

Magnitude

Sets the strength of the vortex field. The larger the number, the stronger the force. A positive number moves the influenced object counterclockwise. A negative number moves the object clockwise.

Attenuation

Sets how much the strength of the field diminishes as distance to the affected object increases. The rate of change is exponential with distance; the Attenuation is the exponent. If you set Attenuation to 0, the force remains constant over distance.

Axis X, Y, Z

Specifies the axis around which the vortex field exerts its force.

Distance

Use Max Distance

If you turn on Use Max Distance, connected objects within the area defined by the Max Distance setting are affected by the vortex field. Any connected objects outside the Max Distance are not affected by the vortex field.

If you turn off Use Max Distance, all connected objects are affected by the vortex field, no matter how far away they are from the vortex field.

Max Distance

Sets the maximum distance from the vortex field that the field is exerted. You must turn on Use Max Distance for Max Distance to take effect.

Falloff Curve

Volume shape

Special Effects

Apply Per Vertex

Sets where the field emanates from the object. If you turn on Apply Per Vertex, each individual point (CV, particle, vertex) of the chosen object exerts the field equally at full strength. If you turn off Apply Per Vertex, the field is exerted only from the average position of the specified points.

If you are using the Attribute Editor, open the Special Effects section to display the Apply Per Vertex attribute. Available for object fields only.

Tip

If you use a vortex field with a particle object, you can set the Conserve attribute of the particle object to influence of the motion. If you set Conserve to 0, the particle object moves in a circular motion. If you set Conserve greater than 0, you get a spiraling motion.
