OSM and Scene Creation

So I've been reading as much as I can on here about using OSM's and the lib, but I'm a little confused on one thing.

When loading an OSM, it sounds like it creates its own sceneManager, cameras, and viewports. Is it absolutely necessary to use these, or is it possible to override them? If so, how do I go about doing so?

Yes, you can use autocreated scene managers (created by the loader lib) or pass your own to the oSceneLoader and it will use them
