Procedural spline-based road generator with IN/OUT sidewalks and curb support. One-click setup, loop/open roads, material slots, and optimized mesh generation for fast level design.Spline Road & Sidewalk Generator is a lightweight Unity editor tool that helps you quickly create procedural roads using spline points. Simply place and move control points in the Scene view and the tool automatically generates a smooth road mesh along with optional IN / OUT sidewalks.Sidewalks include real curb height geometry, making roads look more realistic for city environments, racing tracks, open-world maps, and level design projects.The tool supports both open roads and closed loop roads, includes material slots for road and sidewalks, and is optimized for fast generation and real-time editing.Perfect for developers who want a quick and clean road creation workflow inside Unity.Key FeaturesProcedural spline-based road mesh generationIN / OUT sidewalks with curb height supportOpen & closed loop road supportMaterial slots for road and sidewalksOne-click setup + real-time editor updatesTechnical DetailsUnity Version: 2021.3+ (Recommended)Render Pipeline: Built-in / URP / HDRP (Material dependent)Type: Editor Tool / Procedural Mesh GeneratorMesh Generation: Runtime + Editor supported (Editor focused)Spline Type: Catmull-Rom splineRoad Features: Smooth procedural road mesh generationSidewalk Features: IN / OUT sidewalks with curb height geometryLoop Support: Open road & Closed loop roads supportedCustomization: Road width, sidewalk width, curb height, spacing, UV tilingMaterials: Separate material slots for Road, Sidewalk IN, Sidewalk OUTOptimization: Lightweight & optimized mesh buildingDependencies: None (No external packages required)Included Scripts: Spline system + mesh generators + custom editor tools
