3D Tiles are an Open Geospatial Consortium (OGC) standard enabling visualization of 3D datasets following the OGC 3D Tiles specification. A 3D Tiles layer can display data from online services, a tileset (.json), or a 3D Tiles archive format (.3tz).
3D Tiles layers in a scene
In the ArcGIS Maps SDK for Unreal Engine, geospatial information is organized in layers with specific capabilities. 3D Tiles layers contain many types of data that can be drawn in global and local scenes. See global or local for more information.
With 3D Tiles layers, you can apply mesh modification to remove areas specified by polygon areas. See mesh modification for more information.

3D Tiles services
A 3D Tiles service is a data service that provides the source content for a 3D Tiles layer. You can use the following kinds of URLs to add source content to a 3D Tiles layer in your ArcGIS Map:
- Item page URL
- 3D Tiles service URL
Local 3D Tiles packages
3D Tiles layers can also access data from a local file in the 3D Tiles Archive Format (.3tz) or loaded directly from an uncompressed tileset (.json) file. Tilesets in JSON format are recognized only if they have the file name tileset.json
.
