Paths are either defined by a spline object or a mesh that has an active edge selection. This Helper is meant to serve as a “path feeder” for operators able to work with splines.

List Box - holds the list of picked objects that serve as a “path”

Up, Down - sorts the position of the selected object

Remove - when clicked, the selected object gets removed from the list

Pick Object - click this button to enter object selection mode. Select any mesh or spline object in the scene to act as a path.

Hide - when clicked, the object is hidden in the scene.

Path - check this option to define the selected object to be already a path (Spline objects)

Selected Edges - when checked, the selected object must be a mesh with an active edge selection. Those selected edges will become the path.

Invert - check this option to reverse the path direction.

Rotation - specify any angle, to freely rotate around the perimeter of the path.

Base Axis X,Y,Z - select either axis to define the main alignment that should be used for all further particle alignment processing.

Ticks per Unit - defines the maximum resolution of the time samples possible along the path length. This value is only used when a mesh object, with selected edges, is chosen as a path provider.
