rdSplineTools Tutorial 8 – Converting Landscape Splines to Blueprint

Last Updated: 4th October 2025
Tutorial created using rdSplineTools version 1.32

This tutorial firstly steps through a simple conversion of a Landscape Spline to a BP Spline.

---

Step 1. Create or load a Landscape Spline in a level

The first step is to create a landscape spline in a level, or load a level with an existing one.

---

Step 2. Use the Convert Tool

Now just select the “Convert Landscape Spline” tool from the main ToolMenu

---

Step 3. Select the Class to Use

Now choose the Class you want to use for the spline.

Note that there is a long-standing bug in the UE engine that stops BP based spline components from serializing their point data (Epic has no plans to fix this). This affects BP based actors that contain a SplineComponent in the Blueprint. To work around this, either use an empty BP (or just select the Actor class) to allow rdSplineTools to create an instanced Spline Component, or ensure that any existing Spline Component is a child of the default root component. You can add other components and shift them around after it has been created. Alternatively, use a c++ actor that creates the SplineComponent at construction.

Step 4. Done

That’s it, now you have a BP spline or series of BP splines in your level. – if you ticked “Remove Landscape Splines” they will also be gone.

There will be a new Actor for each spline in the Landscape Spline.

Note: The Tangent calculations will sometimes get some points tangents flipped (not often), check over your splines after creating and just rotate them around by using the Tangent point widget.
