Don, If you could, yes please. I'm not too familiar with the TXPPlugin or the archive. I'm reading in the TXP just using osgDB::readNodeFile ... is there another way I should be reading in a terrapage or is this plugin applied automatically?

Jason, What I've found useful is to include TXPArchive.h from the osgPlugins/txp directory in the source, and link your executable with the osgtxp plugin directly. IIRC, this was easy to do under Linux, but was rather more cumbersome to do with VC++. I've got some sample code that pulls info from the TXPArchive if you want an example. Don > I see.
