how do you edit the campaign map?

I've been learning how to mod and I was hoping maybe I could expand to this part of modding. How do you edit the campaign map, like actually making a whole new map?

It will be easier if you've done some stuff to vanilla map first so you know how text files etc work; try adding a province on an island to existing map,
read all the tutorials;

Start simply just get your basic coastline shape in, in grey (1,1,1 plus) and blue on map_heights.tga - Have 6 plus regions on map_regions (slightly more for bigger maps). Have all other tga's a plain default colour. Something fertile for ground_types. Black (0,0,0) for roughness, features and trade routes. Any climate colour for climates.

Strip down a strat file so you only have one faction and slave. Use that one faction only in descr_regions for your 6 plus regions. See if you can get that to launch before you start adding loads of detail!

Be aware that absolute max. size for any dimension of map_heights is 1021 pixels. And also the larger the map you use the more problems you are likely to have trying to put large contiguous areas of sea in.

This seems a lot more complex than the simple modding I've done before, but I think I'll give it a go. I'll just back-up my game files and try this. Thank you.

Just to stress what gets mentioned in a lot of posts about modding the map...


*don't change too much at a time*. You need to test very frequently as it can be very hard to remember exactly what you changed when you hit a bug that crashes the game on load. Fixing those kind of bugs when you can't remember all the things you've changed can be a ****ing nightmare.
