The attributes are parameters that control shape generation. The shape grammar rules, together with all necessary assets, are bundled in RPKs which can be exported from ArcGIS CityEngine and imported into your Unreal Engine project. The generation process starts with the initial shape (which can be any Unreal Static Mesh or Spline) from which shape grammar rules are expanded. As input it takes a rule package (RPK), an initial shape and a set of attributes. įor questions or enquiries regarding licensing, please contact uses CityEngine's Procedural Runtime (PRT) to generate buildings and cities.
