Uploading a zip file with a 3D Tileset fails to load

I am trying to upload a 3D Tileset to ION and have zipped up my folder with a tileset.json in the folder structure like the following:

this structure inside the ZIP:

march_site_5/

├── march_site_5.json

├── March_Site_5.b3dm

└── …

sometimes I get a resource not found and on the last one, I got no errors, but nothing loads either. Asset # is 3428624. Please help!

Here is the other error I get: We were unable to process your data due to the following issue:

Error: File Not Found
File: march_site_5/march_site_5.json

Read about what data formats are supported on Cesium ion.

I moved this into the “Cesium ion” section, so that the Cesium ion core team can have a look.

Until then, just to quickly confirm:

  • The archive contains a tileset.json at the root?
  • This tileset JSON refers to an external tileset with a URL like march_site_5/march_site_5.json?

Hi,
I see the 404 errors for the 3428624/March_Site_5/March_Site_5.b3dm file when trying to view this asset.

Looking at the data asset there are two March_site_5 folders. One is nested in the other. There is no March_Site_5/March_Site_5.b3dm file but there is a March_Site_5/March_Site_5/March_Site_5.b3dm file.

I would suggest re-creating the zip file to only have one March_Site_5 folder and a single tileset.json file to avoid confusion.

Thank you for the response and suggestions. I repackaged the zip as suggested and still get a cannot find the file. The structure is now
root folder
..\tileset.json
..\march_site_5.b3dm
..\Data

The initial post mentioned a march_site_5.json. I assume that this was an external tileset. Which files does the main tileset.json now refer to? (The point that all this is revolving around is whether the URLs in the tileset.json and all other tileset JSON files are correct or not…)

Can you let us know the asset id for the new asset you uploaded so we can review? Thanks!
