Not sure if its relevant but I notice that .b3d's exported by Quill3d do not have a 'ROOT' node - the first NODE is normally called 'StaticScene'. Maybe all entities are children ??
Try using the b3d2xml code in the archives. You can then read the file to see how its been saved - edit the info and convert back to .b3d.
