Hi Robert, I get some artifact when doing what you suggested. Here is my scene and the setup - a composite viewer with one mirrored view
osg::Group* rootForMainView; osg::Group* rootForMirroredView; osg::Group* scenel rootForMainView->addChild(scene); rootForMirroredView->addChild(scene); rootForMainView->getOrCreateStateSet()->setAttributeAndModes( new osg::FrontFace, osg::StateAttribute::ON ); rootForMirroredView->getOrCreateStateSet()->setAttributeAndModes( new osg::FrontFace(osg::FrontFace::CLOCKWISE, osg::StateAttribute::ON ); viewer->getView(0)->setSceneData(rootForMainView); viewer->getView(1)->setSceneData(rootForMirroredView); now, with this setup, the mirror is displayed ok, but the main view is wrong - looks like CLOCKWISE affect it too, so all the faces are flipped. Any clue?
