Hyper Procedural Spline Toolkit V3 – Unreal Engine

Hyper Procedural Spline Toolkit V3 – Unreal Engine

Author fences, walls, roads and organic spline content with two complementary spline systems: a classic blueprint-based spline for direct mesh-driven setups and a PCG-generated spline for large scale procedural placement. Both are performance-focused and include editor helpers to speed authoring.

Key features:
• Blueprint spline (mesh-driven) — select a mesh and author splines that place and orient that mesh along the curve. Options include forward axis, update spline automatically in editor, spline up direction, rotation inverse and per-point type overrides.
• Point type overrides — set all spline points to one type: curve, constant, linear, curve-clamped or custom tangent. Includes a single-button action to set all points to the chosen type.
• Editor actions for mesh spline — Build Spline, Disable Collision and Enable Collision on generated spline for editor performance and quick iteration.
• Perfect for lerp-mesh workflows — ideal for castle walls, continuous mesh walls, rails and other cases where meshes are interpolated along a spline.
• PCG-generated spline — places individual meshes along a generated spline without deforming the mesh. Controls include override section length, scale min / scale max, rotation variation min / rotation variation max, offset min / offset max.
• Project to landscape — PCG spline includes a Shoot Project to Landscape button to snap placements to terrain. Great for fences, spike walls and procedural boundary elements.
• Decal spawner (spline mesh based) — spawn decal roads and worn paths along splines using spline-mesh decals for quick road layout and visual fidelity.
• Example content — example map with landscape, fences around a small town and small wall examples to demonstrate real-world setups and recommended workflows.
