The Roads Must Roll, a powerful procedural generator for Blender, has received significant updates focused on photorealism, including dynamic wet surface effects, damaged asphalt, and major performance optimizations, transforming ArchViz workflow.
CGI artists often spend countless hours manually modeling and texturing detailed city environments. This complex process just became exponentially faster thanks to the latest feature-rich update to The Roads Must Roll, a procedural streets, bridges, and intersections tool for Blender.
Created by the development team known simply as The Roads Must Roll, this tool leverages Procedural Generation to handle the most time-consuming aspects of city building. The latest versions (1.30 through 1.50) deliver the two most requested features: highly realistic wet surfaces and detailed damaged materials, alongside massive workflow improvements.
Achieving Ultimate Photorealism with New Materials
The driving force behind this update is the pursuit of photorealism. The creator analyzed community feedback and prioritized features that drastically enhance scene realism with minimal effort.
Dynamic Water and Damaged Surfaces
The new water system is a game-changer for Cinematic rendering. Instead of a simple wet layer, the effects now intelligently account for height variations and joint depths, simulating how water naturally pools. Users gain three customizable parameters:
- Wet Surface Amount: Controls the overall dampness.
- Subtle Puddles: Adds realistic standing water.
- Roughness: Defines the reflectivity of the wet layer, simulating drying times.
Furthermore, the tool now includes a new damaged asphalt material and expanded options for sidewalks. Artists can choose from 19 different pavement materials and procedurally adjust parameters like the visibility of utility covers, the percentage of broken tiles, and the overall dirtiness of the surface.
Custom Textures and Expanded Roadside Assets
Recognizing the need for customization, the team added dedicated user material slots. This allows artists to easily import their own PBR textures for all main material types, ensuring the roads blend seamlessly with custom assets and unique local aesthetics. The developer also added seven new roadside materials, covering different looks for grass, dirt, and sand, rounding out the environment design options.
Massive Workflow and Performance Boosts
Beyond visual fidelity, a key frustration point in large scene creation is viewport performance. The Roads Must Roll update tackles this head-on with innovative proxy features, ensuring artists can manage massive city scenes without crippling their hardware.
Smart Proxies for Viewport Speed
To significantly boost viewport performance, the tool now includes Low-Poly Proxies. Users can set the viewport to display ultra-low-poly versions of trees and vehicles (down to 1-2k triangles) while reserving the high-resolution, detailed models for the final render. This streamlined workflow improvement extends to textures, allowing low-resolution textures in the viewport while maintaining high resolution for the output.
Enhanced Traffic and Intersection Control
While the tool does not provide a full physics-based traffic simulation, the updates bring immense control to traffic flow for ArchViz and cinematic projects. Key animation features include:
- Animated Vehicle Wheels: Wheels now rotate dynamically with adjustable speed.
- Low-Poly Driver: An optional low-poly driver is added to vehicles for exterior shots.
- Separate Traffic Curve: Traffic flow can now be defined on an independent curve, simplifying the process of animating vehicles through intersections. If you need help mastering complex junctions, the creator referenced a helpful Traffic Intersection Tutorial video.
New intersection presets, including two roundabouts and a T-junction, help artists quickly block out complex city layouts. Additionally, ten new bridge pillar types have been added, giving structural support more variety and realism.
Expanding the Asset Library: Vehicles and Presets
A major value proposition of this product lies in the included Automotive assets. The creator estimates the value of these integrated vehicle models alone to be hundreds of dollars, offering substantial savings and quality consistency.
- Small Studio License: Includes 6 original vehicles plus 6 new fully integrated cars (total 12).
- Business License: Includes all 12 Small Studio vehicles plus 6 additional large vehicles (trucks, vans, buses), bringing the total to 18 optimized vehicles.
All included vehicle models feature optimized geometry (20k–40k triangles) and randomized colors for quick diversity. The tool also supports using custom vehicle and tree collections, providing maximum flexibility.
For those looking for fantastic supporting assets to populate their cities, the developer noted the excellent use of Greeble Town’s asset packs for background buildings.
Pricing and Availability
The Roads Must Roll is a paid commercial product, priced at $64.98 for the basic license. All updates, including the major feature additions detailed above, are provided free of charge to existing license holders. You can purchase the tool directly on The Roads Must Roll on Superhive or on Flipped Normals.
By continuing to incorporate user feedback through their community survey, the team ensures the tool remains a crucial asset for any professional artist building detailed urban environments in Blender. This Geometry Nodes powered system truly saves hours, allowing artists to focus on the creative direction rather than repetitive modeling.
