Coordinate system for GLTF files imported as 3d tiles

Are there recommendations for the coordinate system that should be used when uploading a GLTF file to be converted to 3d tiles? I have successfully done this but the 3d tiles appear as a flat plane orthogonal to the globe rather than wrapping around the globe as expected.

Hi @ebrelsford, thanks for your question and welcome to the forum. Can you share your data with us so we can try to reproduce the problem internally?
