HI Akilan, The .osga files are a distraction for this topic, it actually relates to any file format that the OSG might load.
The OSG supports multi-threaded database paging using the osgDB::DatabaePager could with osg::PagedLOD / osg::ProxyNode. For you purposes you'll want to use osg::PagedLOD, decorating each of your models with a PagedLOD node with the lod ranges set so that they get loaded when you are in range of them. The OSG will do all the loaded, exprity of unsed subgraphs for you. Lots has been written about paging over the years so please go have a look at the archives. Robert.
