The Hyper Procedural Spline Toolkit v3 (5.5+) is a powerful resource pack for Unity that enables developers to author fences, walls, roads, and organic spline content using two complementary spline systems. The first is a classic blueprint-based spline system that allows direct mesh-driven setups, where users can select a mesh and place it along a curve with precise control over orientation, axis, up direction, rotation inverse, and per-point type overrides. This system supports automatic spline updates in the editor and includes editor helpers to speed up authoring.
The second system is a procedural content generation (PCG)-based spline that places individual meshes along a generated spline without deformation. It offers flexible controls such as override section length, scale variation, rotation variation, and offset variation. A "Shoot Project to Landscape" feature allows snapping placements to terrain, making it ideal for fences, spike walls, and other boundary elements.
Additional features include a decal spawner that enables the creation of road and worn path decals along splines, enhancing visual fidelity for road layouts. The toolkit is particularly well-suited for lerp-mesh workflows, such as castle walls, continuous mesh walls, and rails, where meshes are interpolated along a spline.
The pack includes example content featuring a small town landscape with surrounding fences and wall examples, demonstrating real-world setups and recommended workflows. Designed with performance in mind, it provides optimized editor actions like Build Spline, Disable Collision, and Enable Collision to improve iteration speed.
