Advanced Spline Meshes is a solution for creating smooth and visually consistent mesh deformations along splines in Unreal Engine. It replaces the limitations of Unreal’s built-in Spline Mesh Component, delivering improved stability for complex shapes, and is ideal for tracks, tubes, rails, tunnels, and any geometry that needs to follow a curve in any direction.
Unreal’s default spline mesh system often struggles with twisting, pinching, and flipping when splines fully occupy 3D space. These artifacts are most noticeable when splines loop, twist, or move along the same axis as the spline's up vector.
Advanced Spline Meshes eliminates these problems by generating a clean, stable orientation along the entire spline. Every point shares a consistent frame of reference, so your mesh flows smoothly from start to finish with no unwanted twists or pinching.
Built on the same framework as SplineMeshComponent, this system is designed to feel familiar and gives developers, artists, and technical designers the freedom to build curved geometry of any length or complexity without fighting the engine.
