SB Mapper is a great piece of equipment. It helps you to do terrain maps with small or allmost no effort. Mapper is probably not the right tool for those of you who like to sit hours, days or even weeks working with the maptool provided in SB. And it´s certainly not a tool for those wanting to do a map of a real world area. But for the rest of us... well, try it and if you got it to work, see for your self. It should be said that I can´t get Mapper to work properly my self, eg. it´s only a few heightmaps that I got Mapper to like and all of them are in format 1024x1024.
