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.
