Read/convert KMZs that are missing .dae file


I’m trying to figure something out...

Is there a way to convert KML without the .dae extension to be read in Cesium?

We have a KMZ file that was generated for a building from the Onuma System, but in opening it there is no customary .dae COLLADA file within. I’ve been trying to get it to read in Cesium (haven’t tried the kml branch yet) but I can’t seem to get it to convert to anything meaningful without the .dae file. Will the KML branch of Cesium support KML files, alone?
