Hi Mach, Terrapage databases usually have overly aggressive LOD range settings so it culls out tiles complete at long distances. As others have said the default camera position in osgviewer is beyond the distance range of many Terrapage databases so you have to zoom before it starts paging in. There is nothing wrong here, it's simply the way the database is set up, and the fact that osgviewer is a general purpose 3D viewer so the default camera positions reflect what is appropriate for the broadest range of 3D scenes.
W.r.t memory consumption unless you are in range of the LOD distances you won't see any paging in at all, and the memory won't start increasing either. This is the OSG doing exactly what it's supposed to, it's the whole point of database paging - you only load what is required, and if the database says that a tile ain't in range it simply won't load it. Get in range of the LOD and things will automatically start paging in. For a simulator you'll be controlling the camera position to be within the confines of the model any way so you'll see the terrain pop up. Robert.
