Spline Mesher is a powerful Unity tool that generates clean, customizable meshes along splines for building roads, rivers, pipes, rails, walls, and other curved level elements. It supports smooth deformation, adjustable width and resolution, UV mapping, and seamless tiling for high-quality results in real time. The tool is designed for fast level building, letting you shape paths visually and instantly update geometry as you edit the spline. Easily control materials, snapping, and segment settings to match different styles. Perfect for open-world environments, racing tracks, procedural scenes, and rapid prototyping where flexible curved meshes are essential.
