Labs Road Generator geometry node

Generate roads from curves or OSM data

On this page

This node generates roads from curves, and will handle intersecting curves and create crossings automatically. A good use for the tool is with OSM data.

Tip

Make sure input curves either have a good width attribute or none at all. The tool works best with real world scale inputs. Tutorial on the tool

Parameters

General

Width Scalar

Scales the width of the road.

Road Module Settings

Custom Module

Custom modules for the straight sections of the road can be provided here.

Module Width

Scale the custom module road pieces.

Module Length

Spacing between road modules.

Intersection Settings

Road Length

The max length of the intersection of the solved road.

Roundness

The amount of roundness created in the intersections.

Convexity

Controls the convexity of the intersection.

Resolution

This will increase the resolution used in generating the intersection. Higher value means more polygons.

UV scale

Controls the UV scale on the generated roads.

Advanced

Bridge Support

Allows for the generation of bridges if a bridge attribute has been found on OSM data.

Visualize Type

Visualize the different types of geometry generated with colors.

Outputs

Road Geometry

Outputs the generated road geometry.

Road Lines

Output the sidelines of the road that could be used to make sidewalks.

Point Cloud

A pointcloud which can be used for instancing road modules.
