I was pondering this the other day and it occurred to me that the problem
boiled down to the fact that some (if not all) serializers do not write via a
subclass of NodeVisitor, and hence are unaffected by nodemasks.
I wondered if you could simply make your node so it is ONLY visible to
NodeVisitor traversal by subclassing the node and overriding the traverse
function. e.g.
Code:
class NonSerializedGroup : public osg::Group
{
public:
UnserializedGroup(osg::Group* unserializedGroup)
: _unserializedGroup(unserializedGroup) { }
void traverse(osg::NodeVisitor& nv)
{
_unserializedGroup->traverse(nv);
}
osg::ref_ptr<osg::Group> _unserializedGroup;
}
