ArcGIS CityEngine for Unreal Engine

ArcGIS CityEngine for Unreal Engine is an Unreal Engine 5 (UE5) plugin for generating procedural buildings using CityEngine shape grammar rules. It brings CityEngine’s procedural modeling capabilities directly into UE5, so designers and artists can create and customize buildings without leaving the editor. Buildings remain procedural, allowing their height, style, and appearance to be adjusted through a parametric interface. The plugin also supports building generation at runtime.

The plugin uses rule packages (RPKs) authored in CityEngine. Each package contains a CGA rule file and associated assets that define an architectural style. The download section below provides ready-to-use RPKs to help you get started.

Download the latest release from the downloads section on GitHub and follow the installation guide to set up the plugin. Example projects are available on the ArcGIS CityEngine for Unreal Engine page.
