Not sure what you mean, I've played a lot of toroidal maps, and north and south have always been top and bottom of the map regardless of the maps actual dimensions. How I know, animals are spawning correctly on the map, e.g. mammoths, on the north pole (map-top) and penguins on the south pole (map-bottom).
Disclaimer, I've never tried a tall and thin map type before, perhaps you are, right, that latitude and longitude is then automatically rotated....
I thought Hydro asked if it were possible with a tall and not very wide map where mammoths spawn on map-right (north pole) and penguins on the map-left (south pole).
That latitude were the horisontal axis and longditude were the vertical axis of the map.
Am I wrong Hydro?
