Sandcastle example:

Browser:

Operating System:

dracoGlb.zip 3dtiles with draco , 1.83 good, but newer version failed to view,
I can upload the data to ion, but failed to provide an sandcastle exapmle, I guess ion can not process glb with draco is the reason,
so please just download the zip file, it contains a tileset.json and a glb. you can easily reproduce the problem I encountered.

Hi @geo3data,

There was a major change to how we handle 3D Tiles in 1.97. Does this tileset work before or after version 1.97?

I can upload the data to ion, but failed to provide an sandcastle example

Cesium ion uses CesiumJS to render the examples. If there is an error loading the file, then the Sandcastle example.

I would suggest looking through CHANGES.md for the releases from 1.83 to 1.93 to identify the relevant change.

Perhaps https://github.com/CesiumGS/cesium/issues/9847?

Finally, I found the problem in my code, after draco, mesh vertex number and triangle count all changed, but I did not notice this, I thought they were not changed, so close this issue.
