Plutom, I apologize for the delay in responding but work sometimes interferes with play.  My second apology is for misinformation in the previous message.  I got so focused on recreating the Material Room that I forgot the point of the exercise.  Two things change when I apply one of the options from the Library, the Image Source and the Highlight Size reverts to 100.000 on all the material zones associated with that body part. Face paint = eyesocket, skinface, lip, nostril, and eyebrow that have to be corrected.  Every time I select something new from the Library and apply it, I have to go to the Material Room and adjust the Highlight size on five or six zones.  If I don't, the skin tones are washed out and splotchy and the new eyes are white.  Sorry for the confusion but this is starting to mush what little brain I have left!  I hope this clarifies what is happening and why I want to correct the pz2 files directly.  Thanks
