Guide for making a CK2 Color-Coded Terrain mod, for other maps such as Total Conversion mods.
Copied from Steam description:
Does not change checksum (allows achievements). Up-to-date for 3.3.5.1.
In Terrain map mode, provinces are colored based on terrain. This allows you to tell what terrain each province has without having to hover over them, useful during wartime. (There is another mod on the Steam Workshop that does this, but it has various errors and has not been updated for a long time. It also does not prevent snow from blocking the colors in northern provinces during winter.)
The in-game screenshots shown are with draw_postfx=yes (default; brighter) and draw_postfx=no (darker).
Number of Provinces with each Terrain: RGB, in-game reference if any:
48 Arctic: (255, 255, 255)
626 Plains: (220, 255, 150)
222 Desert: (232, 231, 195), Empire of Turan's color
8 Marsh: (17, 237, 189), Duchy of Kanem's color
28 Farmlands: (243, 180, 17), Golden Horde's color (I wanted to use this for the Steppe but it looks too bright)
195 Hills: (195, 175, 150)
111 Steppe: (210, 160, 50)
122 Forest: (147, 164, 104), Empire of Rus' color
317 Mountains: (145, 145, 145)
62 Jungle: (25, 153, 25), standard green color for things like 0% revolt risk
1 Ocean: (241, 10, 50), County of Wight's color, since it is the only (controllable) province with Ocean terrain
1740 total provinces
Miscellaneous:
Water: (51, 67, 85)
Siberian Wastes and impassable Deserts: (38, 38, 38)
Mountain Ridges: (94, 94, 94)
Special thanks to AhistoricallyCorrect, whose "Very Accurate" Province Terrain Map on Reddit and the Paradox Forum helped verify that I didn't make any mistakes. Of course, there is still a possibility for small mistakes, let me know if I have made any.
Compatibility:
This mod is meant for vanilla provinces. If you use another mod which changes any province's terrain or shape, the colors will not change to reflect it.
This mod replaces these 3 files:
gfx/FX/pdxmap.lua (commented out the line that adds snow to northern provinces in winter: //sample.rgb = ApplySnow( sample.rgb, Input.prepos, normal, vFoWColor, FoWDiffuse ); )
map/terrain/atlas0.dds (made textures transparent so they don't block the colors)
map/terrain/colormap.dds (for terrain colors)
Thus, this mod will not be compatible with any mod that changes those files. You can consider making your own custom version of this mod to be compatible with other mods. E.g. if you are using the In heavens Graphics overhaul mod, and you want to remove snow with the Cancel Snow (IHGO) mod, you can create a private version of this mod that doesn't have pdxmap.lua, so that the Cancel Snow mod can use its own version of pdxmap.lua.
