3D_MODEL + position fails to process via REST API

Cesium ion
1

Hi,

I’m uploading glb files to cesium ion via the REST API and hitting a consistent processing error when combining 3D_MODEL with a position. The asset is uploaded successfully but fails during the tiling stage with a generic red error message on the Ion dashboard.

I created three test assets to isolate the issue:

  • 4454645 — 3D_MODEL + position → ERROR
  • 4454647 — 3D_MODEL without position → COMPLETE
  • 4454648 — 3D_CAPTURE + position → COMPLETE

Same glb file in all three cases. The only variable is sourceType + position.

This worked fine until roughly 2 weeks ago. Is there a known regression in the 3D_MODEL + position pipeline?

Thanks

Nicolas

Hi,

I have done some initial investigation on this and it seems like a bug based on it. I will forward this information to our tilers team to take a deeper look at it. I will let you know as soon as I have an update.

Thanks,

Hi,

As a quick follow up, you can try using the BIM_CAD source type in the meantime with the position. That runs a newer pipeline for 3D Models and might work for your use case while the team is investigating this issue.

Thanks,

Hi Ankit,

Thanks for the quick response. I just tested with the BIM_CAD source type with the position and it works.
