Here is a test render using build 012, XP pro SR3, PP2012 SR1, 32bit (unfortunately).

There was no special lighting used, and different items got different settings to get a little variety.  I thought the road came out great.  I wanted the sign that says "Book Store" to have a little snow on the front, but I couldn't get it to work for me.  Is it possible?

Please tell me that I am not alone in trying to figure out ice.  I can't seem to get it right (there is no ice in this image).  Is it the lighting I am using?
