    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.

The Cesium for Unreal plugin unlocks the 3D geospatial ecosystem in Unreal Engine. By combining a high-accuracy full-scale WGS84 globe, open APIs and open standards for spatial indexing like 3D Tiles, and cloud-based real-world 3D content with the power of Unreal Engine, you are empowered to create a new era of geospatial applications utilizing real world content using game engines.

Cesium for Unreal can stream real-world 3D content such as high-resolution photogrammetry, terrain, imagery, and 3D buildings from Cesium ion and other sources. The plugin includes a Cesium ion integration for one-click access to global 3D content ready for streaming. Ion users can also leverage cloud-based 3D tiling pipelines to create end-to-end workflows transforming massive 3D content into semantically-rich 3D Tiles, ready for streaming to UE.

The plugin supports cloud and private network content and services based on open standards and APIs. You are free to use any combination of sources with the plugin that you please.
