[osg-users] Database pager and failed loading of PagedLOD's children

[Robert Osfield]

As for the particular question, the OSG requests children that are
required for a given range when then come into range, and while they
aren't available will automatically fallback to the next highest level
of detail until this child is loaded.

So... in your case if child 1 fails to load when request the OSG will
just keep fallback back to child 0 automatically.
