How can i see attributes of OSM data？
Cesium for Unreal can show metadata of OSM，however，when do select by keys, i have no idea about key value, and OSM data come from cesium ion.
Another, Can CesiumEncodedMetadata modify metadata?

I’m not quite sure where you’re running into trouble. You say “Cesium for Unreal can show metadata of OSM.” What are you trying to do beyond that? Or you believe it’s possible, but you don’t know how to do it? If that’s the case, check out the Metadata level in the Cesium for Unreal Samples project:

It’s not currently possible to modify the metadata. If you want to modify the metadata for Cesium OSM Buildings specifically, I suggest you make contributions to OpenStreetMap.

Thank you for response at first.
Maybe i want to add 3d data with metadata or attribute, then show the table of info, it is like OSM metadata Sample project. I have not find a suitable way based on Cesium for Unreal.
And, i know Datasmith supported by UE5 can import BIM model, and the same time, i can use it’s metadata by self, however, i dont want use datasmith data.
So, i want to find a new way to do the same thing.

Well, I can’t walk you through how to build your application, but if I’m understanding you correctly… you want to associate your own metadata with features. To do that, just use the combination of the tile component’s name (which is set from the tile URL) and the feature ID of the particular building within that tile as a key into your own map/database of properties. How you actually represent/store/persist that mapping of tile features to properties is up to you and needs to be entirely implemented in your own application (there’s nothing built into Cesium for Unreal to help with that).

yuan1405 · September 5, 2023, 8:37am

@Kevin_Ring I guess you means is that one Cesium3dTileset tiles contains a 3Dtiles within that 3Dtiles have feature ID and other info. As so, many Cesium3dTileset will exist in an Unreal level.
My the earliest plan is want use data online to improve FPS and performance.

Kevin_Ring · September 5, 2023, 9:44pm

A single Cesium3DTileset contains many tiles, yes. Typically there aren’t very many tilesets in a level, though.

yuan1405 · September 6, 2023, 1:05am

@Kevin_Ring yes, I cannot sure it will have a result, but i can do a test according to your advice.

yuan1405 · September 6, 2023, 6:40am

@Kevin_Ring Sorry, Can you give me a link of OpenStreetMap Building Data with per-building metadata? I donot find the original Data, maybe json or kml and so on?
Thank you very much.

Kevin_Ring · September 6, 2023, 8:41am

I’m not really sure what you’re asking for. The original data is from OpenStreetMap:

If you’re asking for Cesium OSM Buildings, that’s only available in from Cesium ion and only provided in 3D Tiles format. The 3D Tiles contain per-building metadata.

yuan1405 · September 6, 2023, 9:20am

@Kevin_Ring ok, maybe i should make a sense of 3d Tiles at first. Thank you for the explain in detail.

How can you print attributes of OSM Cesium metadata:

download example project:
Cesium for Unreal Samples in Blueprints - UE Marketplace
Open map 10_CesiumOSMWindows_Metadata, and add print instruction in level Blueprint:

How found metadata in own b3dm model?

open example with metadata object. This is nice example:
Cesium Sandcastle
click F12 and download any model b3dm with metadata:

image1781×557 220 KB

https://assets.ion.cesium.com/us-east-1/asset_depot/75343/NYCDoITT/v1/5/9/23.b3dm?v=2
open model in notepad and look batch header table. First line look like this. You can fine metadata like Heigh and other:

But You cant easy change this data! This is binary format and have checksum :/.

3D Tiles 1.1 with gltf:
Now Cesium work on gltf file wtih separate json file. But it doesn’t work in the UE yet
Nice tool for migrade b3dm to gltf file is:
GitHub - CesiumGS/3d-tiles-tools
You can convert b3dm to glb:

npx 3d-tiles-tools convertB3dmToGlb -i ./0.b3dm -o ./0.glb

Then conver glb to gltf using Visual Stuido Code and gltf plugin.

@m.kwiatkowski okok, thank you.

Now I know How add metadata to glTF . Here is topic with working example:

github.com/CesiumGS/cesium-unreal

Rework `UCesiumEncodedMetadataComponent` -> `UCesiumFeaturesMetadataComponent`

CesiumGS:upgrade-feature-metadata ← CesiumGS:encoded-metadata-rework

opened 06:59PM - 11 Aug 23 UTC

Part of the large metadata system overhaul. This PR does the following: - Dep…recates `UCesiumEncodedMetadataComponent`. - Includes backward compatibility, so styling should still work. - Removed "Auto Fill" and "Generate Material" functions, to encourage people to upgrade to the new component. - Adds functions for handling different methods of encoding in `CesiumEncodedMetadataConversions.h` - Deprecates internal namespace `CesiumEncodedMetadataUtility`. Use `CesiumEncodedFeaturesMetadata` instead. - Incorporated ability to parse RGB colors from string from [`metadata-colors`](https://github.com/CesiumGS/cesium-unreal/tree/metadata-colors) (delete that branch after this change?) - Adds support for encoding implicit feature IDs (passes them in a texcoord like other feature ID attributes) - Adds `UCesiumFeaturesMetadataComponent`. - Now displays descriptions of feature ID sets, separate from property tables - Property table properties now display their _actual_ type info via `FCesiumMetadataPropertyDetails`. This way, unsupported properties can show up and users can decide if want to try encoding anyways. - Encoding info is displayed / changed via `FCesiumMetadataEncodingDetails`. - This allows the user to specify how a property should attempt to be encoded, e.g. "Coerce" or "Parse Color From String". - This can be expanded in C++ for custom encoding functionality. - "Generate Material" now generates nodes for feature ID sets without requiring them to be connected to property tables - "Generate Material" detects when trying to change an asset with unsaved changes, to avoid a crash - Updates the upgrade guide for most of the changes Example styling on San Francisco Ferry Building, using "Parse Color from String" as encoding method: ![image](https://github.com/CesiumGS/cesium-unreal/assets/32226860/99405c92-48f8-404a-af35-23c54c1565cf) This PR does NOT address the following: - Property textures - ~Normalized properties (will leave comment)~ - ~Null feature IDs -- will result in undefined property access in materials, e.g. random property colors will show up~ - ~Feature IDs aren't working for point cloud attenuation because the vertex factory isn't passing them in. It seems like the texcoord-related parameters are never binding, but I don't understand why :/~

Here is example with metadata:
https://github.com/CesiumGS/cesium-unreal/files/12613418/TestStructuralMetadata.zip

If you want make own metadata. You need add attributes _FEATURE_ID_0 tabel in Blender:

than connect this table to vertex:

and export model with attributes like glTF:

Then make file.bin with metadata for example:

Red are height, yellow is elementID
FLOAT32 big-endian hexa 0x00002041 = 10
FLOAT32 big-endian hexa 0x0000F041 = 30
FLOAT32 big-endian hexa 0x00004842 = 50

elemetID:
INT32 hexa 0x00000000 = 0
INT32 hexa 0x01000000 = 1
INT32 hexa 0x02000000 = 2

Here is my example with blender
budynki.zip (217.5 KB)
This zip example is in Warsaw Poland:

I change teksture when metadata is 30:

Cool, glad you got it working. Thanks for sharing @m.kwiatkowski!
