I was using the camera to do a background layer scroll like mentioned in http://www.cocos2d-x.org/forums/6/topics/27653?r=41573#message-41573. or http://www.learn-cocos2d.com/2012/12/ways-scrolling-cocos2d-explained/ (scrolling with camera).
Since now camera is removed from node. any idea on how to do this ? any pointers would do.
