The Roads Must Roll - Procedural Streets & Bridges

by Astopia in Modifier Setups



A new road generator that allows you to create detailed streets, bridges and intersections in minutes, not days.

Everything is procedural and based on curves. Made for Cycles.









Based on curves

150+ configurable settings at your fingertips.






One tool, many Roads

A city street, highway, bridge, traffic junction, ... the choice is yours.






14 Procedural Props

From bicycle bridges to traffic lights and road markings, we've got you covered.






Preset Intersections

A collection of pre-made intersections, so you can get started right away.




Procedural Everything

Customize every prop with ease—just head to the modifier panel to personalize your scene.




6 Cars included

Meticulously hand-modeled with performance in mind.






Night time is the right time?

Turn on the lamppost lights and car headlights with just one click.






Based on the real world

3D models based on the real world just look better.






Parking made easy

Choose from six different types of parking strips to park your cars just right.






Performance options

– Choose less resource intensive textures for your materials
– Optional low poly trees
– Optional low poly cars
– …





High quality materials

Our materials are ready to render






Animate your cars

Easily animate cars along a curve, using either your car models or ours.
Control speed, spacing, density, and direction to suit your needs.






From 1 to 10 lanes

Choose the number of lanes that fit your project:
Single deck: 1, 2, 3, 4 or 5
Double deck: 2 x 2, 2 x 3, 2 x 4 or 2 x 5



Bike Lanes

A unique feature of The Roads Must Roll! Bike paths can be on the ground or a bridge.





Create in minutes, not days

Freeing up more time for the creative aspects of your work.

Made for Cycles


"The Roads Must Roll" currently works with Cycles only, as not all materials seem to work with EEVEE.



Current Limitations


Converting the road to a mesh or exporting to another software package


While it’s possible to convert the road into a mesh and then export it to other software, there are currently some limitations.

For more details, please see the FAQ on our website

All materials with road markings won't properly convert  to a mesh. And most materials are unlikely to successfully convert to another software package.


Using 'Material Preview' mode in the viewport


Since 'Material Preview' relies on the EEVEE render engine, it’s not supported at this time.


Traffic Simulation


You can easily animate cars on each road object individually, with adjustable parameters like the density of cars, their random seed, spacing, and speed. Each road object is based on a single curve.

However, this is not a full traffic simulation, as vehicles do not interact with traffic lights, intersections, or each other. If you want to animate cars driving through an intersection, you will need to do this manually.

Currently, the wheels of the cars do not rotate when the cars are in motion.


Custom Lane Width


The lanes are currently a fixed width of 3.5 meters (11.48 feet). I'm planning to make this adjustable in the future.



Everything included:

  • A new procedural asset for traffic: animate vehicles on an independent curve
  • Numerous small menu improvements
  • Performance enhancements for the fully procedural asphalt material
  • Super texture resolution option
  • Updated procedural assets


Version 1.22

27-09-2024


I’ve added the option to generate the white (and yellow) lines on the asphalt as geometry, as an alternative to adding them directly within the asphalt material. You can also adjust the height of these lines. Good news if you want to convert the road to a mesh. See the FAQ on our website.

At the very bottom of the settings in the main road modifier panel, I’ve created a new panel called "Convert to Mesh Preparation" Here, you can check the 'Realize Instances' box. For more details, see the FAQ on our website.

If you've chosen a custom car collection, you can now rotate all the cars simultaneously around their own axes.

You can now also use your own tree collection.

Increasing the subdivision of the road surface now works more effectively.



Version 1.21

Resolved a minor issue where the diagonal bars on the overhead signs were disappearing.
