Click on “EDIT” and select a control point to change the parameter's settings. “@ CP radial” introduces a force around the control points.
@ CP @ CP vortex
Click on “EDIT” and select a control point to change the parameter's settings. “@ CP vortex” creates a rotational force around the spline's path. Positive values create a clockwise rotation, negative values create a counter-clockwise rotation.

Every control point can be linked to another node, e.g. to animate a point's position. Normally, “Null” nodes are used for this purpose, but any other node will work as well. Simply click Click on “-” to open for a node list.
@ CP handle smoothness
With “Smooth” both tangents are affected while moving a single handle. When you switch to “Broken” the tangents can be edited separately.

weighting
When set to “Even” both tangents have the same influence on the spline's curvature. With “Uneven” the tangents' influence is treated individually.
