Hi David, I can't recall all the options off the top of my head so with the help of osgdem --help and grep I get:
$ osgdem --help | grep LOD --LOD Create a LOD'd database. --PagedLOD Create a PagedLOD'd database. --subtile <LOD> <X> <Y> -l <numOfLevels> Specify the number of PagedLOD levels to generate. So the last one is the one you want, so just add a -l 5 or something similar to your osgdem or vpbmaster command line. Robert.
