So in looking through the map making and tutorial sections on the boards, the one thing that I have not been able to figure out is how to draw borders for my map. I have an image, in the proper format and able to be loaded up by dominions 3, and when I load it, there are a couple hundred indy flags in the NW corner of the map. Where along the way can I draw borders and have the map editor read them? Thanks for the help everybody, sorry this is such a newb question, I've done plenty of modding, just virtually nothing with modding maps.
