I had to play with the model, by loading the previous version, resizing the new one and trying to get the postion the same,and then I deleted the older one from the screen, so I wouldn't have to relight the whole thing again.  I've been speding time adjusting the lights, since I couldn't quite match up the two models, and tweaking the textutes, since I forgot to make some of them parametric when I was loading everything.
