Features

Everything you need to build a track

From the ground up: shape the landscape, lay the road, sculpt every cross-section and finish it with realistic materials. Then dress it with objects, walls and trackside furniture that stay attached to the world as it changes.

Adjust the track and the terrain follows in seconds. The road is cut into the terrain automatically, with boolean operations "eating" away the polygons beneath it, and objects, walls, string objects and start/finish positions reposition themselves when you change the ground beneath them.

Alpine terrain generated from Google Maps data

Real-world or hand-crafted landscapes

Terrain

Build terrain from Google Maps imagery and height data, or sculpt and paint your own. Tracks are cut into the terrain automatically as you lay them down.

Trees and fencing generated along a track, with the Generate window open

Dress a whole track in seconds

Generation

Generate decals, bumps, objects, string objects and walls along your tracks in one go, with templates to reuse your favourite setups.

A track being cut into the terrain

Fast, powerful and automatic

Track Editing

Drag out miles of road in minutes. Track cutting, joining and automatic camber are handled for you, with heavy calculations running in the background.

Editing the cross-section points of a track

Shape every metre of road

Cross-sections

Change road widths, angles and randomness in seconds, and create bumps, dips and gutters of any description.

Two roads merging at an intersection, blended into grassy terrain

Roads that belong in the landscape

Blending

Materials, geometry and lighting are blended so road edges melt into the surrounding terrain, with optional terrain snap for roads that flow with the hills.

Track materials applied to a road surface

Realistic textures, easy editing

Materials

Drag and drop materials between sections, position them with gizmos, and use specular, bump, add and multiply maps for realistic surfaces.

Tyre stacks, cones and a gazebo placed around a track

Dress the scene

Objects

Place objects from a growing library. Parent-child relationships add automated variety, collision meshes and level-of-detail models.

Concrete barriers, painted walls and catch fencing following the terrain beside a track

Barriers that follow the ground

Walls

Drag walls out across the landscape. They rise and fall with the terrain and track, and adjust automatically when either is edited.

A row of pit garages built as a string object from start, pattern and end pieces

Bollards, blocks and more

String Objects

Draw strings of objects such as bollards and blocks, then move them around the landscape. They follow the terrain as it is edited.

Pit lane and starting grid paths laid out beside the pit garages

Pit lanes and timing

Start / Finish

Place pit lanes, start/finish lines and timing gates directly on the track.

Burnout skid marks and a chequered start line laid as decals on the road

Detail on every surface

Decals

Lay decals over the road and terrain to add markings, skid marks, patches and other fine detail.

A trackside camera and its view frustum beside the track, with the Generate Cameras window open

Frame the action

Cameras

Generate trackside cameras around the whole lap in one click, with varied heights, offsets and zoom for broadcast-style replays.

Pacenote markers placed along a forest rally stage, with the pacenote palette across the top

Call every corner

Pacenotes

Add pacenotes along rally stages so co-drivers can call the corners, crests and hazards ahead.

Spotlights lighting a dirt road at night, with each light’s cone outlined

Racing after dark

Lights

Light up the track, pits and scenery for dusk and night racing.

A vast mountain range generated from real-world height data

Room for the longest tracks

Expansive worlds

Start with more than 1,300 km² of terrain and expand it whenever you need room for longer tracks or scenery.

Terrain

Real-world landscapes

Race Track Builder taps into Google Maps to retrieve imagery and height data, producing accurate, beautiful landscapes on which to lay out your vision of the perfect race track. Add more detail to the terrain and RTB retrieves the extra height data automatically.

Prefer to build from scratch? Create your own mountains with the built-in terrain tools. Use the built-in materials, tap into a growing library of expansion packs, or make your own textures.
