why is cesium ion saying the tileset location has not been set for the 3D tiles when I’ve provided a .prj file with the obj on initial upload?

Hi @a.okeefe289,

I think this question may be more relevant to the #Cesium ion category. I’ve moved you question there.

Thanks!

Hi,

Our tiling pipeline currently doesn’t read `prj` files for location information. Would you be able to reupload the obj with a KML sidecar file or the location information embedded in the obj itself.

Thanks,  
Ankit

I’m sorry, I’m quite new to the OBJ file - would you mind assisting me in how I could embed the location information? Or create a KML sidecar file?

Hi,

How are you currently generating the obj file? The options might be specific to the software being used.

Thanks

Hi Ankit,

I’m creating and exporting it in CloudCompare
