There is DepthSortedBin as well osg::ref_ptr<osg::Group> group = new osg::Group; osg::Node* one = createHUD(); // this will be your background image osg::Node* two = scene.get(); one->getOrCreateStateSet()->setRenderBinDetails(1,"DepthSortedBin"); two->getOrCreateStateSet()->setRenderBinDetails(2,"DepthSortedBin"); group->addChild(one); group->addChild(two); one->getOrCreateStateSet()->setMode(GL_DEPTH_TEST,osg::StateAttribute::OFF);
