I was working on a new map that depicts an underground dungeon. I wanted to achieve a similar effect to another map I had done http://www.cartographersguild.com/showthread.php?19724-Al-Qadim-(-quot-Nine-Flawed-Sapphires-quot-).
It was getting terribly annoying to keep opening up the old map to see what setting I used so I decided to create a little reminder for myself. In the process I thought that maybe I would just create a little mini-tutorial on my method. I don't claim that this is a great method (or even a good one) but it works for me until I figure out a better way. Its attached in PDF format...enjoy.
