描述

Discovered while testing Sandcastles for the 1.75 release. This appears to be an issue in the last release too.

  1. Go to the Export KML Sandcastle (https://sandcastle.cesium.com/index.html?src=Export%20KML.html)
  2. Choose "Model" and "Download"
  3. Open this KMZ in Google Earth

It fails to load with the following error:

I can open this COLLADA file successfully in Blender:

We should investigate if this is something we're incorrect/invalid in the sample model we're using here that Blender is accounting for.

研究方向
Investigate the COLLADA model used in the Export KML Sandcastle. Compare its structure with models that open correctly in Google Earth. Check Cesium's KML export logic in the source code (likely in Source/Widgets or Source/DataSources). Consider testing with a simpler model to isolate the issue. Look for any known compatibility issues between Cesium's COLLADA output and Google Earth.
