Hey On the page http://www.openscenegraph.org/index.php/download-section/stable-releases I found download URL for 3.4.0: http://trac.openscenegraph.org/downloads/developer_releases/OpenSceneGraph-3.4.0.zip which is not working. The whole site http://trac.openscenegraph.org/ is down. -- Best regards, Boris Nagaev
