Vandy -- outer bevel would not work at all...run thru it and try it yourself and you'll see why...the shapes would not look like roofs at all, they'd look like berms or mounds. You're also probably used to having the light source in the upper left and therefore everything seems to be opposite of what you're used to...remember my sun for this is in the lower right. The river...well I wasn't too concerned about making terrain for this tut, the emphasis was on making buildings.
Red -- Yeah I had it in the back of my head to try and keep this as simple and generic as possible to see what can be done by you guys who really know your stuff. Taken one step further you could generate paths with the selection based on the streets. Putting down the streets and the 1-pixel eraser cuts are hand done but the rest should be able to be automated. Oh and thanks![]()
