Can cesium process a KML with 3D model information in it?

My server-side generated KML from my previous GoogleEarth-based web app used to use 3D models, building the placemarks as so:

                " <Placemark id = """ & mmsi & "3d"">" & vbNewLine & _
                " <Model id=""model_4"">" & vbNewLine & _
                " <altitudeMode>relativeToGround</altitudeMode>" & vbNewLine & _
                " <Location>" & vbNewLine & _
                " <longitude>" & longitude & "</longitude>" & vbNewLine & _
                " <latitude>" & latitude & "</latitude>" & vbNewLine & _
                " <altitude>0</altitude>" & vbNewLine & _
                " </Location>" & vbNewLine & _
                " <Orientation>" & vbNewLine & _
                " <heading>" & heading & "</heading>" & vbNewLine & _
                " <tilt>0</tilt>" & vbNewLine & _
                " <roll>0</roll>" & vbNewLine & _
                " </Orientation>" & vbNewLine & _
                " <Scale>" & vbNewLine & _
                returnDemStr(type, Double.Parse(length), Double.Parse(beam)) & _
                " </Scale>" & vbNewLine & _
                " <Link>" & vbNewLine & _
                " <href>http://xyz.com/dae/TNK.dae</href>" & vbNewLine & _
                " </Link>" & vbNewLine & _
                " </Model>" & vbNewLine & _
                " </Placemark>"

I've successfully converted the .DAE file into a Cesium-formatted .GLB, but simply changing "TNK.dae" to "TNK.GLB" in the KML doesn't seem to work. Is there a way for cesium to parse a KML file and read its 3d model placemark data?

Hello,

As far as I know, changing the path to point to the .glb file should work. Are there any error messages in the console when you try to load the KML?

Best,
