Collada Model Rendering Issue in Cesium ion

We’ve encountered a problem when adding a Collada model to our assets for tiling.

The model displays correctly in Blender, online 3D viewers, and SketchUp. However, when we attempt to view it in Cesium ion, it appears as shown below (You can see the holes):

This is what it looks like on

For reference, I am also attaching the .dae file (2.7 KB)

There are some polygons with 5 vertices and it seems that the holes are exactly where these polygons are.

Any suggestion or tip on how to handle collada files?

We apologize that you are having issues with this file. I have opened up an issue for our team to investigate this problem further. We will let you know when we have any updates.
