I haven't installed my Black Friday Poser 9 yet, so I guess I will have plenty to learn; and appending lights is just one of many useful techniques to get used to. I can imagine the scene library would be useful for those folks who produce serial stories, as a way of starting with the major characters and maybe the surroundings in place. When I want to do this, I just load the previous scene file and delete all the stuff I no longer need.
