Bug Reports / Issue with exporting Cesium Tiled Models - Version Mismatch

« on: February 12, 2025, 03:20:15 PM »

Hi everyone,

I've encountered an issue while exporting Cesium tiled models using Metashape.
Regardless of whether I export the tiled model in Cesium format 1.0 or 1.1, tileset.json file, I noticed that the asset version is still indicated as 1.0.

Code: [Select]

"asset": {
        "version": "1.0"
    },
I tested this issue in versions build 2.1.3.18946 and the latest 2.2.0.19890 release of the software.
I am using a Windows 10 environment for this process.

I made a few test on CesiumJS code

Code: [Select]

console.log("3D Tiles Version:", tileset.asset.version); // 1.0
Analyzing the tiled model using the 3d-tiles-validator node provided by Cesium, it reports the use of the 3DTILES_content_gltf extension.
From my limited knowledge, this extension should be deprecated and unnecessary in 1.1 because you can use glb by default.

Is this a known bug, or am I missing something in the export process? If it's not an error, how can I differentiate between the two formats?

Any assistance or insights would be greatly appreciated!

Thank you!
