Hi Guy,
The use of compile contexts looks to be very dependant on OS and
OpenGL driver. What OS/hardware and drivers are you using? Have you
tried any other platforms. It'd be useful to see if there is a
pattern.

It sounds like the compilation of display lists, VBO's and texture

Are you aware of VirtualPlanetBuilder and osgEarth? They both provide

them. VirtualPlanetBuilder is an offline too, while osgEarth can do

Hi John,
yes, you can traverse through the node hierarchy you get when you load
the file. You can use osg::NodeVisitor for that.

Yes. Everything works when I don't use the compile context (i.e the scene is
rendered correctly), except that I still detect a problem with the number of
