CesiumIon asset 35183 - how to add custom properties ?

1. A concise explanation of the problem you’re experiencing.

How to add custom properties into OBJ or DAE so the properties (like building name etc) exist in B3dm tiles?

Am confused of the workflow, where can I read more?
Would like to manually test, given a 3d model OBJ/DAE, what software to use to add custom properties like building name?

Assuming conversion to GLTF->GLB->B3DM preserves the properties.

2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

Trying to creating B3dm tiles (from OBJ or DAE files?) with custom attributes, just like New York City 3d tiles,

so user can hover and display feature (building) information

4. The Cesium version you’re using, your operating system and browser.


There is currently no supported workflow for tiling OBJ/glTF models with metadata into 3D Tiles. The New York city example was using CityGML as the source data, which does support embedding metadata per-feature like that.

We’ve got a feature request here to add this soon: https://github.com/AnalyticalGraphicsInc/cesium-ion-community/issues/132
