Can CityEngine export 3D GIS data to Unity or other VR/AR visualization engines?

Yes. CityEngine is well suited to export your 3D GIS data or city models to Unity, the tool of choice for developing Virtual Reality applications (for example, Gear VR, Hive, and Oculus) or Augmented Reality solutions (for example, HoloLens). As a result, CityEngine writes the popular FBX file format, which can now be flawlessly read by Unity. In the typical use case, an FBX so-called "instancing" feature allows for small file sizes and high frame rates in Unity.
