Installing this asset also adds several enhancements.

Spline Container inspector

You’ll find that the Spline Container inspector now shows a few new buttons:

1: Open/close the Spline editor
2: Draw new Spline
3: Paint new Spline
4: Toggles debug info, such as spline lengths and bounds
5: Opens the context menu
6: Dropdown for adding new processor components

The context menu (6) contains a few utility functions:

Name	Function
Flatten (XYZ)	Positions all the knots to the current center of the Spline’s bounds, on the given axis. Useful when splines need to be flat.
Flip (XYZ)	Mirrors the Spline on the given axis
Center Pivot	Moves the position of the container’s Transform to the center of its Splines and shifts all knots in the opposite direction. This results in no change to the shape of the spline curve(s).
Reverse Flow	Rotates the knots in the opposite direction and reorders them. For some tools, this may be necessary to get correct results. As this changes what is considered right- and left.
Apply Transform	Repositions the knots and rotates them so that the Transform can safely be reset back to (0,0,0) without changing the apparent curve of the Spline
Remove Twists	Resets the X and Y rotation value of all the knots to 0. Used to ensure rivers or roads are leveled.
