Procedural Road System [v1.0.0]

The Procedural Road System is a powerful Unreal Engine plugin designed to streamline the creation of dynamic and realistic road networks. Whether you’re building an open-world city, simulation, or racing environment, this system enables developers to design roads, intersections, and traffic systems with ease, all fully procedural and highly customizable.

The Procedural Road System eliminates the manual effort of setting up complex road networks. It intelligently adapts to terrain, manages dynamic traffic, handles pedestrian systems, and even responds to time-of-day and weather effects. This makes it an ideal tool for developers who want to focus on creativity rather than technical overhead.

Features

  • Procedural Road: Quickly set up complex road networks, including 1-way and 2-way configurations.

  • Road Intersections: Seamlessly connect multiple roads with intersection types such as Crossroads and T-Junctions.

  • Auto Landscape Adjustment: The landscape dynamically deforms to match road elevations and curvature.

  • Custom Actor Spawning Along Roads: Automatically spawn roadside elements such as streetlights, barriers, or signs.

  • Pedestrians: AI pedestrians dynamically spawn and navigate along sidewalks and crossings.

  • Pedestrian Crossings: Integrated traffic lights control pedestrian movement and vehicle stopping behavior.

  • Vehicles: AI-driven vehicles spawn and follow road paths intelligently.

  • Vehicle Collision Detection: Vehicles detect obstacles and react dynamically to prevent collisions.

  • Smooth Vehicle Movements: Adaptive speed control and predictive steering provide realistic driving motion.

  • Road Traffic Transitions: Vehicles and NPCs intelligently transition between connected roads and intersections.

  • Buildings: Procedurally placed buildings help visualize urban layouts alongside the road network.

  • Weather Effects: Dynamic puddle formation and surface wetness during rain enhance realism.

  • Time-of-Day Effects: Automatic toggling of streetlights and vehicle headlights based on lighting conditions.

  • Zones: Define specific spawn zones for pedestrians and vehicles for controlled simulation areas.

  • Smart Spawning: Optimized spawning logic based on player proximity and occlusion for performance efficiency.

  • Dynamic Weather: Smooth transitions between weather states such as sunny, rainy, or cloudy.

  • Procedural Roads: Rapidly prototype and visualize road networks for world-building.

  • Advanced In-Built Debugging: Visualize runtime states and AI behaviors in real time for easy troubleshooting.

  • Component-Based Pluggable Architecture: Modular and extendable system that integrates cleanly into any project.

  • Data-Driven Architecture: Fully configurable through data tables, eliminating the need for direct code changes.
