Hi J-S,
The serializers uses the library name and the class name to look up
the wrappers to read and write the objects. If the library name and
class name are different from osg and Group then it won't invoke the
Group wrappers. To have .osg support for them you'll need to provide
a wrapper, or

The dotosg wrapper / serializer recognizes classes from there class

By default the OSG computes the near/far planes on the fly during the

Alternatively you could just use the gl_ProjectionMatrix directly on
