I have an example of loading before the scene is loaded, and in a callback. If you have an example with Promises instead of callback nesting, that would be more ideal, the second $.getJSON() (child scenegraph) might finish before the first $.getJSON() (parent scenegraph) if I don’t use promises or callback nesting. Also, Promises would allow me to separate the parent loading somewhat from the child loading, and create separate functions. Also, X3DOM experts can provide an example with Promises as well.
