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.

Scatter vegetation, grass or anything you can think of.

Thank to the curve based scattering generator, you can easily scatter any mesh of your choice onto the terrain, it will automatically avoid scattering on roads, tunnels, bridges or trails.

The scattering tool comes with a LOD system.

Comes with a extra tools to facilitate game engine export.

Roadscape comes with 3 external addon tools, Roadscape Utility Tools, for anything related to the workflow. Procedural UV to Real UV, which helps converting the procedurally generated UVs to game engine UVs in two clicks. And OSM Vertex Cleaner, which cleans any OSM imported path from its excessive attribute count, based on Roadscape ready presets.

Comes with a detailed written documentation.

We constantly update the product aswell as the documentation.

And so much more...

This product page is currently under re-construction. More will be detailed soon, in the meantime here's a list of some of the functionalities.

• Side Object Instancing: Easily instantiate objects along the sides of your roads, including street lights, barriers, and custom objects, with options for randomization and terrain alignment.

• Road Details Scattering: Scatter road details like cracks, potholes, and debris along your roads for added realism.

• Curve Scattering: Use curves to scatter vegetation or other objects, with options for distribution on zones or lines, LODs, and terrain normals.

• Winter and Spring Weather Presets: Switch between winter and spring environments with corresponding material changes and visual effects.

• Noise Displacement: Add noise displacement to roads, terrain, and trails for a more natural and rugged appearance.

• Game Engine Ready or Procedural Texturing: Enjoy dynamic texturing for trails, ensuring seamless transitions between different materials.

• Advanced UV Controls: Fine-tune UV scaling and materials for road, support, trail, and roadside elements directly from the main menu.

• Lower Trail Centers: Mimic real-world trail characteristics by lowering the center of trails, creating indentations for added realism.

• Recalculate Terrain Normals: Fix terrain normal issues with a single click, ensuring proper shading and lighting on your landscapes.

• Preview Subdivision in Performance Mode: See the results of road subdivision adjustments directly in performance mode, making it easier to optimize your road models.

• Unmatched Flexibility: Roadscape takes flexibility to the next level, allowing you to model large-scale and complex road systems effortlessly. Design intricate road networks, intersections, and various road types with ease, adapting to any terrain mesh.

• Performance-Oriented: The addon is engineered for performance, ensuring smooth operation even in large and detailed scenes. Create vast road networks without compromising on speed and efficiency.

• One-Click Road Generation: With a single click, Roadscape generates a complete road mesh, including road sides, camber, and elevation adjustments. This one-click simplicity makes it accessible to both beginners and advanced users.

• Procedural Generation and Texturing: Roadscape procedurally generates and textures road meshes, ensuring clean quad topology and seamless integration with your terrain. The road markings are also procedurally generated, saving you time and effort.

• Customizable Road Features: Have full control over road width, road support width, camber, and elevation at any given vertices. Fine-tune your road design to match your project's requiremens

• Custom Road Markings: Create custom road markings with ease.

• Bridge Generator: Design realistic bridges with improved column placement and terrain interaction.

• Guardrail Generator: Draw curves to generate guardrails automatically, adapting to intersections, bridges, and tunnels.

• Vegetation Scatter: Scatter vegetation along your roads for added realism.

• Tire Marks: Add tire marks for a more dynamic road appearance.

• Local Procedural Terrain Subdivision: Control the terrain subdivision locally, optimizing performance and detail where needed. This feature ensures a seamless blend between the road and terrain.

• Terrain Smoothing: Smooth your terrain to enhance the overall realism of your scenes, creating a more natural-looking environment.

• Output Options: Choose to output either the modified terrain or the road network only, providing flexibility in your workflow.

• Clear and Intuitive Interface: Navigate through Roadscape's features effortlessly with a clear and refined menu system. Access all tools and settings from a user-friendly panel, ensuring a quick and efficient workflow.

PLEASE! Note that this addon is a one click tool but it isn't beginner friendly, you need at least a general comprehension of Blender in order to use it with ease.
Make sure to read the documentation in order to see what you're getting into before buying.

Disclaimer (Limitations): Roadscape can only work well with a low poly terrain mesh. High mesh density terrain will result in a very long processing time that will make the tool unusable.

The addon is designed to be user-friendly, but a basic understanding of Blender is recommended for optimal usage.
A decent system is required to run Roadscape properly. I recommend at least a 5600X level CPU or equivalent.
