This session shows how to use ArcGIS CityEngine urban designs and procedural models in game engines and related technology: this includes exporting to Unreal Engine, Twinmotion, Unity, and Godot; and syncing models to NVIDIA Omniverse. It also shows how game developers and designers can use game engine scripting to replace CityEngine assets and materials with high quality game engine assets to dramatically improve the look of imported models. Finally, we show how the CityEngine procedural runtime (PRT) can be used directly within Unreal Engine for real-time procedural content creation.
