Reverse the flow of a spline
Reverse the flow direction of a spline.
Each spline has a flow direction that moves from its first knot to its last knot. Arrows on the segments and knots of a spline indicate the flow direction of the spline.
If you reverse the flow of a spline, you create a spline that mirrors the original spline. The following occurs:
- The knot indices of the spline reverse. For example, the first knot of the original spline becomes the last knot of the reversed spline.
- For knots in the Bezier tangent mode, the In tangent becomes the Out tangent and the Out tangent becomes the In tangent.
To reverse the flow of a spline:
In the Hierarchy window or Scene view, select a GameObject with a Spline component.
In the Tools overlay, set the tool context to Spline.
- Select a knot on the spline.
- In the Scene view, right-click to open the context menu.
- In the Scene view context menu, select Reverse Spline Flow.
