Procedural road systems usually break in the same place: the junctions. Roads arrive at every town at different angles and heights, overshoot the center, hook back on themselves, or just stab into a single point like spokes on a wheel.
This video shows how I fixed it in WorldGen — turning routed paths into real spline-mesh roads, then connecting them cleanly at every settlement.

The trick on junctions: docking each road by its actual approach direction (where the A* path arrives), not the straight-line bearing to the next town. Two roads become a through-road; three or four add perpendicular T-branches.
Built on top of the procedural road & settlement system from the previous video — settlements are still deterministic, roads still RNG-graph between them, terrain still grades to the road. This update makes them look and connect like real roads.
Covered in this video:
✔ Spline-mesh roads tiled along smoothed splines
✔ Smooth plan curve + linear height (no floating on slopes)
✔ Bed-matched width — geometry sits on the carved roadbed
✔ Road meshes stream around the player (configurable radius)
✔ Optional collision on road tiles near the player
✔ Square junction box with N/E/S/W ports
✔ Approach-direction docking (not straight bearing)
✔ Through-roads for 2-road towns, T-branches for 3-4
✔ Junction branch overlap to close T-joints cleanly
✔ Debug shape toggle for tuning settlement density and junction size
