+Required: 
+
+- Installation Unity3D with plugin 'Cesium for Unity3D' - current version is 1.6.2
+
+- Use -f cesium in previous step tesselate_building.
+
+Copy the generated tiles to webserver (for example $ python3 -m http.server)
+
+- In Unity3D open sample Assets - CesiumForUnitySamples - Scenes - 05_CesiumMetadata
+
+- In the hierarchy navigate to CesiumGeoReference - NYC Buildings - Inpspector
+
+- In the Inspector change 'Tileset source' from 'From Cesium Ion' to 'From Url'
+
+- In the Inspector change 'URL' to the url pointing to tileset.json

+In the Game View the buildings should be visisble, when using --create-gltf false as option in pg2b3dm (so b3dm's are created), the metadata 
+also shows up.
