It should be supported.
I just tried it out, and it seems to work for me…
If it does not work for you, then the usual first questions would be
- Which FireFox version are you using?
- Which Operating System?
- Are there any other suspicious messages in the console?
This will probably have to be part of the description for any issue that may be opened in Issues · CesiumGS/cesium · GitHub
In this time I couldn’t get conditional styling based on metadata to work. All examples I found seem to use
features(e.g. here) instead of metadata. What is the syntax to access metadata when applying a style or ist there no comparable build-in way?
I think that the example at How to filter 3D tiles by group defined in 3DTILES_metadata Extension or 3dtiles 1.1? - #2 by Marco13 already shows one way. As I said, there are some questions about the exact structure if this is supposed to be done in a “real” application, but … does that example work for you in principle?
