Smart Spline Generator v4.27+ is a powerful Blueprint-based resource pack for Unreal Engine that enables the creation of surface-aligning assets such as ivy, vine, ropes, bridges, fences, and more. The tool generates assets that automatically adapt to any surface with high customization options, offering a wide range of parameters to control generation behavior, including spline direction, sub-spline amount, mesh count, height above ground, random irregularity levels, and alignment rotation. All parameters are clearly described in tooltips and in-depth documentation provided within demo levels. The pack includes a set of default presets that users can modify or extend, and supports the use of custom meshes. With the UE Merge tool, generated assets can be converted into static meshes for reuse across levels or exported for further editing in 3D software. The system features automatic bridge mechanics that detect nearby surfaces and allow control over bridge gravity, as well as low-poly edge snapping to prevent issues near surface edges. Automatic mesh optimization replaces most spline sections with low-poly versions, preserving only critical areas like edges and corners. Fully developed in Blueprints, the tool is fast, intuitive, and highly effective for creating realistic, dynamic environmental elements.
