Issue about not rendering Delaware polygons into Unity

[Mitko88]

I've followed the steps as suggested, but I get an error in Unity. What could go wrong?

[2024-05-30 17:25:56.823] [error] [ErrorList.h:72] Errors when loading tileset:

• Error when parsing tileset JSON, error code 3 at byte offset 0

The error is not very specific, that is why I've shared a link to the generated tiles:

can you try with parameters '--create_gltf false --use_implicit_tiling false'

[Mitko88]

Thank you for the quick reply. I've used these two parameters.

pg2b3dm -h localhost -U postgres -c geom_triangle -t delaware_buildings -d postgres -a ogc_fid --shaderscolumn shaders --create_gltf false --use_implicit_tiling false

I've tried to visualize the tiles in Cesium ion, and I do not see any polygon.

looks alright like this, should be able to visualize the results in CesiumJS/Cesium for Unity. I'll take a look later

[bertt]

tried it, works alright for me... One difference I see it's:

Tiles created: 60
External tileset.json files: 8

versus:

Tiles created: 238
External tileset.json files: 27

Do you see something in CesiumJS when doing step 'Visualize in CesiumJS'?

What version of tessalate_building did you use? (should be 0.3.0)

What's the used database?

select version()

select postgis_full_version()

[Mitko88]

I've figured out what is the issue. I did not configure the server properly to call the tileset.json. I've visualized the tiles properly in Unity now.

Thank you for the help!
