MagicSpline is a plugin allowing the creation SplineMeshActor in your levels to generate and edit meshes following a spline mesh (static meshes or spline meshes with deformation). It’s a powerful level design tool that can be used in many ways (walls, roads, pipes, chains, fences, blocking volumes, etc.) in an optimized way.

it’s an optimized C++ plugin but you don’t need to know programming to use it. Like in the video in the description, you just have to create a new blueprint based on the class SME_SplineMeshActor. Then you can add this blueprint actor to your levels and just edit the settings in the details panel. The plugin will be automatically installed on your engine.

If you know C++ and would like to add some extra functionality to this plugin, it’s also possible as the source code is provided.
