Vitruvio brings ArcGIS CityEngine’s procedural modeling power to Unreal Engine. It enables generating procedural buildings using CityEngine's generative runtime and shape grammars. Generated buildings remain procedural at all times. Attributes such as height, style or appearance can be modified in real-time to generate new building variations. Vitruvio can also be used in a packaged product and buildings can be generated dynamically at runtime.

Important: Proceed to the official GitHub page to download Vitruvio. The latest release is not available in the Epic Games Launcher any longer.
