Metromake 1.0.0

Road network editor features

Metromake 1.0.0 is a native desktop editor (C++, OpenGL) for building road networks lane by lane, with terrain and water, and exporting them to driving simulators and 3D engines.

01 — Roads

Roads and cross-sections

Spline roads with any cross-section. Everything on the road is generated from it and rebuilt live while you drag.

  • 10 lane types: driving, parking, bus, bike, shoulder, hatched, median, sidewalk, verge, barrier
  • Per-lane width, direction and height; 11 marking styles
  • Curbs, markings, crosswalks, bridges and street lights generated from the cross-section
  • Drag lane boundaries in the cross-section preview; save custom profiles

02 — Junctions

Junctions and roundabouts

Automatic junction surfaces for any number of roads.

  • 6 controls: priority, traffic signals, all-way stop, give way, uncontrolled, roundabout
  • Roundabouts size themselves to their roads, with flared entries, an island and a truck apron
  • Corner radius, crosswalks, stop lines and turn arrows per junction

03 — Signs

Signs with OpenDRIVE codes

27 sign types after the German StVO / Vienna Convention designs, including speed limits 10–130 km/h and their ends, and traffic lights. Each carries its OpenDRIVE code.

  • Placed beside a road, facing the traffic on that side
  • Stay attached when roads are split, joined or reversed
  • Exported to OpenDRIVE as signals, and to glTF/OBJ with their texture

04 — Terrain and water

Terrain and water

Sculpt the ground and add water; roads keep their shape when the ground moves.

  • Sculpt with brush, area and road-corridor tools
  • Water: basin fill, brush, ponds and rivers that flow downhill
  • 8 map templates: flat, water, plains, hills, mountains, islands, lakes, river valley
  • Lower the ground under a road and it becomes a bridge with piers

05 — Views

2D blueprint view and 3D view

Switch between a 3D view and a 2D blueprint view with contour lines and a height cut.

  • Height cut: hide everything above a level, for example to see under a bridge
  • All editing tools work in 2D too
  • Light and dark themes

06 — Projects

Projects of several maps

Place maps side by side on a shared plane; roads continue across map edges.

  • Drag maps into place; edges snap to neighbours
  • Binding points join roads across map edges, with matching lane profiles
  • Terrain blends along shared edges
Plan view of one road network split across four maps of a project, with roads crossing the map edges.
