we are trying to generated gltf from dae file ,using the existing converter tool provided by cesium org as given in the below link:
once we dragged and dropped the existing and working dae from google earth, the generated gltf is inappropriate as we are unable to render the generated gltf with code of
cesium sandcastle example of 3D model .
could you please let us know whether we have missed out on anything in the process of generation of gltf.
