Is there a way to accomplish this? > > The important calls for setting up a hud camera are:
camera->setReferenceFrame(osg::Transform::ABSOLUTE_RF); camera->setClearMask(GL_DEPTH_BUFFER_BIT); camera->setRenderOrder(osg::Camera::POST_RENDER); camera->setViewport(x, y, w, h); And maybe also: camera->setAllowEventFocus(false); If that doesn't resolve it, you'll need to post some code and a screenshot. -- http://www.ssTk.co.uk
