Edit: See this instead: http://fodev.net/forum/index.php/topic,29557.0.html by Realism. It's 100% better :>
This is a script I made using Python (3.x version) for the mapper. I tested it in FOnline: 2238 Mapper, version 1.29.0.
I don't know if someone else has already made something like this, or how useful it is as opposed to just copy-pasting, but anyway...

###
The first part of the script makes random desert tiles at any HexMax x/y to start. Note that it currently doesn't look too "natural" and looks somewhat repetitive compared to, for example, e_desert1.
The second part of the script makes the exit border around the generated map.
It should be ready to view in the mapper after writing to file (first load might take longer before you save it using the mapper).
The script will write to file in the same directory that the Python script is in.
Feel free to use/improve the code for any purpose, it's not too convenient at the moment. If I have time, I'll finish/improve the parts of the script that make the exit border, and probably some more natural-looking random attributes. There's probably some off-by-one errors possible on the map borders and scroll blockers, depending on if the number is odd or even.
