Loader

3d-tiles

Description

When I create a tileset.json with distances that span continents and zoom into the location where the tiles are located, the tiles are not loaded. If they are not combined they load. In my case the two locations are vienna and calgary. Have you ever tested your library against such a tileset? If you have it is probably an issue on my side that I haven't considered yet. I also tried it with a 3d-tiles loader I wrote myself and there the tiles load.
If you think it is necessary I'd gladly setup a minimal reproduction of this issue.

Expected Behavior

Tiles are loaded even for distant tiles.

Steps to Reproduce

sample_distance.zip

Here is the sample dataset, the two locations are Canada Calgary (51.0449, -114.0730) and Austria Vienna (48.2102, 16.3706).
The .glb files themselves are projected differently than specified in the 3d-tiles standard, so if they are loaded, you wouldn't see them in e.g. the Cesium viewer. However, they should appear in the network tab.

    "@loaders.gl/core": "4.3.2",
