I found a reasonably good generic solution to flatten any part of my scene graph. - Use a visitor pattern to collect all my osg::Geometry into a set of geometries starting at the osg::Group in question - do a clone of the geometries into a new set with (osg::CopyOp::DEEP_COPY_PRIMITIVES | osg::CopyOp::DEEP_COPY_ARRAYS) , then add them into a new osg::Group for the optimizer to work with. - Use a osgUtil::MergeGeometryVisitor to collect all the primitive sets - Then an osgUtil::IndexMeshVisitor to merge the primitive sets
