I'm afraid I'm too busy to go into this stuff. There has been plenty of discussion on osg-users over the years so have a browse through the archives.

Robert, thanks for the quick reply! However, that brings me to the next question... The DatabasePager is using addChild to add loaded nodes to the PagedLOD. Let's say that my initial (unloaded) structure is: First child is "referencing" to "level_1.ive" Second child is "referencing" to "level_2.ive" Third child is "referencing" to "level_3.ive" When all request has been made and the DatabasePager has fully loaded and added the children of the PagedLOD, it is then possible that the first child of the PagedLOD is actually the "level_2.ive"-node??? /Mikael Quoting Robert Osfield <[EMAIL PROTECTED]>: > On 6/13/07, Johansson Mikael <[EMAIL PROTECTED]> wrote: > > When using PagedLOD-nodes the required unloaded child-nodes are requested > from > > the DatabasePager during traversal.
