OpenFlight files aren't paged, you can't just magically page them
without creating PagedLOD nodes that decorate them.  You have to
create some kind of paged database, even if you are creating it
dynamically on demand.

Also OpenFlight is appalling format for doing format as its 10 times
slower than using native binary formats.  Your best best to process
your source data in such a way  as to build a paged .ive database that
is composed of hierarchy of tiles.

Robert.
