In the version 4.2, I added the getCreator method to HomePieceOfFurniture class, but the value won't be null only for models added from that version. Too bad that could have helped you to build faster the list of contributors…
If you want to distribute your final work with JavaFX, the GNU GPL might not be appropriate since it's more restrictive than the GNU GPL with class path exception used by OpenJFX.
Hum, I feel like I should choose Free Art License or CC-BY license if I don't want to restrict the kind of use you look for. Just tell me, because I don't intend to close source the samples in the gallery.
The goal is to provide an X3D test model for my coming JavaFX X3D importer.
Interesting 
How Java 3D and the 3D API of JavaFX compare at the moment?
What other file formats will it support?
