Roadscape 4.x is a Procedural Road Generation Suite.
Geometry Nodes based for Blender 4.5.

Introducing the new OSM Lazy mode.
No need for complex intersection designing anymore, simply draw a road crossing another, and the process handles the intersection by itself.

Now automatically generates roads from OSM/Blender GIS imported paths.
Simply import the OSM path and the road is generated automatically, with elevation change and intersections handling.

Note: At the moment, automatic road generation from OSM paths can only support relatively simple/small sized road networks.
We are working on optimizing the OSM mode to handle larger scenes.

Create embedded curbs sections.
Turn any regular road into a street/city ready road with embedded curbs.

The road will extrude itself into the terrain, and the terrain will adapt to the extrusion, making your road truely embedded into the terrain mesh.
Works with any intersection you can think of.

Easily add marking lines to your road designs.
Effortlessly add any kind of markings to your roads, they will automatically place themselves right where you need them, in between lanes, in the middle of a road, etc…

Add guardrails, jersey barriers or any custom mesh.
Simply draw a curve and instance whatever you can think of. You can target different aspects of the generation, road sides, support sides, sidewalks, trails boundaries…

Turn any road into a tunnel or a bridge.
Every road is one vertex group assignement away from becoming a tunnel, a bridge or a trail.

A complete set of custom markings.
Whether it be racing grids, parking spots, custom islands, regular lines, crosswalks, checkered, white or yellow.

Everything automatically adapts to the road.
