Uncovering the Best CityEngine Alternatives for Urban Design
CityEngine is a powerful standalone software widely used by professionals in entertainment, architecture, urban planning, GIS, and 3D content production. It excels at conceptual design and modeling for creating 3D cities and buildings, boasting features like GIS/CAD data support, OpenStreetMap import, dynamic city layouts, rule-based modeling, and extensive 3D format compatibility. However, for various reasons – be it cost, specific feature needs, or platform preferences – many users seek a robust CityEngine alternative. This article delves into some of the top contenders that offer similar capabilities for your urban design and 3D city generation projects.
Top CityEngine Alternatives
Whether you're looking for a free, open-source solution, a specialized plugin, or a more budget-friendly commercial option, the alternatives below provide diverse approaches to 3D city modeling and urban planning.

Suicidator City Generator
Suicidator City Generator (SCG) is a fantastic open-source script for Blender3D, making it an excellent free CityEngine alternative for users already familiar with or willing to learn Blender. It allows you to automatically create entire, three-dimensional modern cities in seconds by adjusting various parameters. Available on Mac, Windows, and Linux, SCG supports 3D modeling, gaming, and procedural modeling workflows, much like CityEngine's core capabilities.

Modelur
Modelur is a commercial 3D application for parametric urban design, implemented as a plug-in for Trimble SketchUp. This makes it a strong CityEngine alternative for those who prefer working within the SketchUp environment. Available for Mac and Windows, Modelur focuses on providing a streamlined parametric design workflow for urban planning projects.

Building Generator
Building Generator is a free procedural building generator script specifically designed for Autodesk 3ds Max 9 SP1 and above on Windows. If your workflow heavily relies on 3ds Max, this script serves as a valuable CityEngine alternative for quickly generating building geometries and engaging in procedural modeling within your familiar software.

citycad
CityCAD is a commercial urban design software tool geared towards conceptual 3D masterplanning of sites ranging from 1 to 200 hectares. Available for Mac and Windows, CityCAD allows users to sketch street layouts and perform various urban design tasks, presenting itself as a direct CityEngine alternative for comprehensive masterplanning projects.

Blended Cities
Blended Cities is another open-source city generator for Blender, making it a powerful free CityEngine alternative for Mac, Windows, and Linux users. It specializes in rapidly creating large quantities of streets and buildings with diverse shapes, catering to 3D modeling and gaming applications with its procedural generation capabilities.

ghostTown
GhostTown is a free city generator and tool for creating urban environments within Autodesk 3ds Max on Windows. It offers features for both low-poly and high-poly buildings, a road tool for basic layouts, and easy material handling. For 3ds Max users, ghostTown provides a compelling CityEngine alternative for 3D modeling, gaming, and procedural modeling tasks.
Ultimately, the best CityEngine alternative for your needs will depend on your specific project requirements, budget, preferred operating system, and existing software ecosystem. We encourage you to explore these options further to find the perfect fit for your urban design and 3D city generation workflows.
