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!

Hello Leo,

We are planning to implement some fixes for Cesium 3d tiles 1.1 export in Metashape 2.2.1 (build 20082) update. When we have pre-release version updated I will ask you to check, if the reported issue is resolved.
Best regards,
