Set the control point's individual vortex strength. Positive values create a clockwise rotation, negative settings create a counter-clockwise rotation around the spline's path.
Axial
Set the control point's individual axial strength. Positive values create an attraction effect towards the spline, negative settings create a repulsion.
Radial
Set the control point's individual axial strength. Positive values create an attraction to the spline's control point, negative settings create a repulsion effect.
