Hi, captureCurrentState name is misleading - it is not capturing state from OpenGL. It should be, maybe, getCurrentState. It is just taking last pushed attributes on the state stack. These attributes are returned in the StateSet given as parameter. Thus, the function should work any time

The terrain tile is not using paged LOD. When converting the openflight file external models results in ProxyNodes with a reference to eg. house1.flt. The proxynode looks fine in the osgt format, and i guess the reader should have used the openflight reader when loading the converted osgt/b
