Thanks again. Funny about the subway floor, (although in the reference photos they are surprisingly clean–I think they keep that one clean for the tourists) I turned off all the grunge decals 'cuz they were getting on the video plane. But then I found the “Receive Decals” check box! Changed my life. The grunge will be back! It was about 1995 when I was in St Patrick’s so I forgot to bring my I-phone and PolyCam 
Thanks for all your great comments.
