Notes
The yellow and green areas you will sometimes see is terrain that has been painted by map editors, there is currently no way to remove this, make sure that grass density is on high as this will cover most of it.
Tunnels are just normal roads which are covered by a model, so it’s not possible to have them without snow.
It’s not possibe to have some areas without snow as assets are shared throughout the map.

Important!!
Frosty is a winter weather and graphics mod, using other weather/graphics/lighting mods will effect the lighting/graphics/snowfall made for this mod and may cause conflicts and crashes.
Frosty should be placed on top in Mod Manager, if you are also using any of the addons then place them above Frosty.
