Newbie Question About Nodes In Scene Graph

I’m new to JMonkey and game development, so my question is basic. If attach an object to the root node and that object is not viewable to the user, does JMonkey still attempt to render it? My concern is that a world that is really large bog down the game’s performance as the engine attempts to render a large number of objects that are not visible. I would appreciate the input. Sorry for asking such a basic question. LOL!!!

objects that are not in the visible camera frustum are culled (not rendered) automatically by the engine. You can see this for yourself by looking at the “vertices” for example in the stats view, in the basic game test. Look at the cube and look away, the number changes
