Blueprint Spline Editor Tool Reference

This page contains information on tools and procedures for editing Blueprint Spline Components and Blueprint Spline Mesh Components in the Level Editor. As of 4.13, Blueprint Spline Components can also be edited in the Blueprint Editor Viewport using all the tools and procedures below.

Tools

With a Spline Point (selecting a Spline Curve selects the last point on it) selected in the editor, you can use the standard manipulation tools (move, rotate, and scale) to select and adjust the positions and tangents of the spline curve's points.
