Im sure there is someone out there who can and have the ability to create textures. Need to make one that has pattern recogniton. To where you can import specific blocks to specific pattern like this paver pattern as in http://shacktoshowcase.proboards.com/index.cgi?board=ppf&action=display&thread=410.. . Like a basic brick paver (The Romans roads were brick pavers).. to preset town , kingdom etc.
