World Map HD v1.2 is a texture pack changing visual appeal of Mount & Blade's main map.
World Map HD v1.2 for "A Clash of Kings 2.0" mod Diferences from original "World Map HD v1.2": - since texture names are changed in this mod I couldn't find proper snow texture (tested few names but no results) - mod seems to be using new world map texture type "swamp"
Why awe there no snow textures?
As far as I remember there were some issues with including it but I can't recall what kind exactly. If you feel like doing it, then you can always copy&paste; this texture from standard package of this pack (tho I suspect texture names are different)
