Ante Bellum - Map Borders Overhaul

Have you ever grown tired with how sloppy and inaccurate the map looks like in vanilla EU4? This submod aims to change it and replace all the inaccurate terrain with something more sophisticated while being as compatibility-friendly as possible. With this addon come reworked coastlines, terrain textures and provinces' borders for most played regions of the world. While new coastline adds a lot of missing irl features, reworked provinces offer much more detailed borders (especially showing actual bordergore that was the HRE) of both historical and alternative scope. At last, expanded wastelands create more strategic passes and holdings.

- Reworked regions include: Central & North America, ALL of Europe, Middle East, Indian Ocean, ALL of Africa, ALL of Asia
- Reworked, much more detailed coastline for all of regions above
- Redrawn provinces' borders in listed regions. Those allow for recreating most of real-life borders throughout game's history without adding any new provinces.
- Overhauled and detailed terrain textures. This comes down to editing terrain.bmp file, which gives land its colour and texture. In vanilla EU4, this is eather sloppy or inacurate in some places.
- Removed desert terrain in north of Florida (YES, it was a thing), Central and Northern India, Azerbaijan, Burma, Thailand and Central China
- Western Persia is now drylands instead of desert
- Italy, Spain, Provence and Greece have brighter, much warmer terrain texture to represent mediterranean climate
- Removed sloppy lines between terrain types in many regions, instead adding much smoother transition
- Added hill/montainous terrain textures to many missing ranges and highlands
- Swamp regions are better distributed across Polesie and Northern Europe with better blending
- Expanded lakes in few regions (look at the Finland! also Ethiopia and Aral Sea)
- With new coastline comes a bunch of smaller islands that were missing in base game (look Mediterranean and SEA)
- Venice is no longer a big omnious blob floating on the Adriatic Sea (it's still an island province)
- Expanded wastelands pose more strategic value and have been toned down in thickness in many places
- Added JAN MAYEN island back to the map (it was forcefully submerged before). Currently part of East Iceland province.
- Adjusted few rivers to have more accurate flow. Most of provinces' borders follow rivers much better.
- Toned town the heightmap in Himalayas, so zooming in gives you some space to navigate
- Reworked green areas in Middle East
- Arabian Peninsula is now mostly deserted wasteland with only few pockets of settled land. Much like it was for the most of history. New "islands" and oasis in Arabia are still accessible.
- Harshed the desert in North Africa. Provinces are now limited to only include its oasis and main caravan routes (as it was for the most time irl).
- All new oasis and pockets of settled land in Arabia and Africa are accessible through adjacencies. Zoom out to see all of them. This allows for some new strategic unit navigation.
- Islands in the Indian Ocean have been toned down and placed in its more accurate locations (ex. Island of Mahe was located off its correct location, on the sea basin)
- transition between desert and lush forests in Sahel is much smoother. Pushed arid transitional zone more to the north.
- Sahara Desert is much more detailed in terrain features and new terrain changes follow elevation much more accurately
- Brought back many strategical passes (like Java and Sumatra)
- Many mountain wastelands have been greatly expanded to include new strategic passes
- added 1000 islands around Korea, Japan and Indonesia
- Polynesian Islands are MUCH more detailed and there's more of them
- Many more minor terrain tweaks


The mod aims to be as lightweight and as compatible with other non-map-editing mods as possible, so this addon only affects the bare minimum of files. Those iclude:
provinces.bmp heightmap.bmp terrain.bmp rivers.bmp positions.txt adjacencies.csv elevated lakes folder
(any mod that edits the files above won't be compatible with this addon)

Mod is currently designed for version 1.37 of EU4.
As this mod is currently an addon for main Ante Bellum, it must be loaded AFTER Ante Bellum in order to work properly. It was made specifically for Ante Bellum 1.9.1 update and WON'T work with any prior version.
Mod should easily be compatible with any other addon for AB that doesn't edit files listed in paragraph above.
This addon should also compatible with most of graphical mods out there as you can see on the screenshots.

Suggested load order for the mod (load from top to bottom):
- [Graphical mods]
- Ante Bellum 1.9
- THIS MOD
- ...
- [rest of Ante Bellum addons]


- Will this mod update other regions of the map?
- Mod's end goal is to eventually update the map and terrain of nearly every region in the game if the time will allow.

- Why isn't vanilla EU4 supported? Will there be a version for base game?
- The mod was created as an extension to Ante Bellum first. Port to vanilla version will be created after this mod updates most of the regions of the world.

- I don't like X feature of this mod. How do you change it?
- If you don't like certain aspect of this mod (like province design in some regions), your are free to edit the mod files yourself. It really isn't hard. All you need to do is open mod's folder and edit necessary files with editing tool like GIMP to your wish and desire.

- Bordergore in the HRE gives me seizures.
- AEIOU

- Some borders look oddly familiar.
- There are few regions in which province borders were inspired from old and forgotten mod - Historical Additions: Borders +. Though those were altered in a way to better fit the addon's style.

- I love the coastline and terrain changes but provinces' borders aren't my thing. Will there be a version that leaves vanilla borders?
- As it was suggested, such version is planned to be eventually made but that's scheduled after vanilla version of this mod.

- I don't have this game on Steam but I'd like to try this addon. Where can I download the files?
- Mod is available on Github. You are free to download it.
