Thanks Korash I'll give that a try. The mate that sent me the maps did so as PNG files that he created so I'm opening them in PS and trying to give them that 'old school' feel - a bit like the maps in Goodmans DCCRPG range (without the great art) as individual files. When I'm happy with each (from memory there are 4 different ones but 7 floors) I'll try and combine them as you suggest. I'll start a WIP thread once I get the basement done and each floor.
