The maps along with all of the other graphics are sitting in the Images folder as PNG files there for all to see and access.. After I have done the map, I will offer it to Slitherine if they are interested in it though.. if they want to release it officially as part of a patch then thats fine.
Joe - the hexes are an option setting, so you can still turn the hexes on and off as you please, I simply turned them off as I didnt want them to get in the way of my good work when I dumped the images to showcase it
One thing I dont like is how the engine puts some shading and shadows in the hexes over the map. I dont know why it does that.. would be good if that was an option you could turn on and off also. And Im not sure what the Darker Map option does in the options settings.
If someone from Slitherine or Matrix who has been involved in the games development could touch base with me that would be great.
