baz,

which borders? maptex or lukmap?

you prolly want to read the thread on lukmaps posted above in the stickies.

changing the lukmap map can be quite tricky, as some are finding out. this is the map(s) that controls the functionability of the campaign terrain, and there is a LOT of stuff connected with it, whereas the maptex maps are just a simple visual display that match up in size with the lukmaps and are, in essence, an overlay of the lukmap maps and these can be edited without changing any of the functions of the game.

in all honesty, i've not worked much with either of these yet, so i dont have all the answers. barocca has done some stuff with the lukmap maps, but i dont know if he's got a full altered terrain campaign going yet or not. others have modded the visual aspects and this is much easier to do.

you also have to worry about other files when altering the lukmap maps; things like the minimap map and a number of other files and settings. a LOT of stuff in the early, high, and late.txt files are linked and coordinated to the lukmap maps, like where you put the castles, ports, origin points and so on. it's NOT a straight alter-the-lukmap-and-i've-got-a-new-campaign sort of thing. there's a lot of stuff that is all tied into the lukmaps.

read the lukmap thread for some more info on this.
