I've got a tutorial written for this, but I'm still searching for a new ISP so my site is offline. I put the tutorial pages ONLY on an edu server at work until I get my site up at it's own server. Links do not work on these pages. This is in two parts. Photoshop makes the map, but you could probably use another image editing app... Once you have the map, all work is in Bryce. No post production required. Part I: Photoshop http://www.usm.maine.edu/~scottk/alternate/plight.html Part II: Bryce http://www.usm.maine.edu/~scottk/alternate/blight.html Hope this helps. -ScottK
