Faulty triangulation

[jopenei]

Hi,

I am trying to export 3DTiles from a 3DCityDB instance. However running the command (with and without reprojection)

citygml-tiler -i CityTilerDBConfigReference.yml --crs_in EPSG:25832 --crs_out EPSG:4978

results in faulty geometries.

Geometry from py3dtilers

Geometry from FME 3DTiles Writer

Exporting my data as gltf from the 3DCityDB directly does not reproduce this behavior.
