Vitruvio - CityEngine Plugin for Unreal Engine 4
Vitruvio is an Unreal Engine 4 (UE4) plugin which enables the use of ArcGIS CityEngine shape grammar rules in UE4 for the generation of procedural buildings. With Vitruvio, game designers or artists do not have to leave UE4 to make use of CityEngine’s procedural modeling power. The buildings stay procedural all time and artists can change the height, style and appearance of buildings easily with a parametric interface. In addition, buildings can also be generated at runtime.
As input Vitruvio requires rule packages (RPK) which are authored in CityEngine. An RPK includes assets and a CGA rule file which encodes an architectural style. The download section below provides links to the several RPKs which can be used out-of-the-box in Vitruvio.
The latest release is available on the Unreal Marketplace (or in the downloads section on GitHub). Examples can be downloaded from Vitruvio Plugin page. Please make sure to install Vitruvio before running the examples.
Vitruvio is free for non-commercial use. Commercial use requires at least one commercial license of the latest CityEngine version installed in the organization. No redistribution is allowed. Please refer to the licensing section below for more detailed licensing information.
