ArcGIS CityEngine is a 3D software for urban design and modeling cities. The cities you create using CityEngine can be based on real-world GIS data or showcase a fictional city of the past, present, or future.
The Omniverse Connector for CityEngine allows users to conveniently send 3d city models to an Omniverse server for simulation, collaboration, and high-end visualization. The Connector supports lightweight iteration on individual city parts by non-destructively updating previous exports.
