Hi Jason, W.r.t you question about osgSim::OverlayNode, yes it works with paged databases.

I see. I guess that brings me to my next question: Can you use an overlay node on a terrain that is being paged? I was hoping to use the bounding box corner as an origin for grid lines that I draw over the terrain. I can probably find a work around to the bounding box issue, but if I can't lay those gridlines down on a TXP terrain because it is being paged then it would be good to know before I come up with another solution.
