Free Godot 4.4 Addon: 3D Road Generator with Lane Traffic (TheDuckCow)

Overview

TheDuckCow shares a Godot plugin for creating flexible 3D highways and streets with traffic support. Roads are built from RoadPoints grouped in RoadContainers with cross-section based geometry, click-to draw with collision snapping, procedural intersections and prefab four way, three way and highway ramp containers.

Auto-generated AI paths and a RoadLaneAgent helper let agents follow lanes, and road sections can be exported to gLTF/glb. The main branch supports Godot 4.4+, demo scenes start from road_demos/demo_menu.tscn, and the MIT-licensed plugin is a free download from GitHub.
