B3dm with ktx2 tileset issue

Cesium for Unity
1

My b3dm data uses ktx2.0 compression.
I think Tileset is making an error because of this
Can’t I necessarily use ktx2.0 to use b3dm data?

I think gltf 2.0 supports ktx2, but why can’t I use it in the b3dm that wraps it, is there an official document that states this?

@gjqjfjwl321 Can you share the error message you are receiving, and what version of Cesium for Unity you are using?

The error message says that there is no data to be found, but no error message appears due to the addition of new data.
“Cesium for Unity” is the 1.23.1 version
Unity is using 6000.4.1f1.

Thanks for the version info. This looks like another b3dm issue in Cesium for Unity. We’ve filed it at cesium-unity #698.

In the meantime, converting your tileset to 3D Tiles 1.1 using 3d-tiles-tools might help:

npx 3d-tiles-tools upgrade --input ./tileset.json --output ./tileset-1.1 --targetVersion 1.1
