What this mod does
GMC Graphics Fidelity Winter Addon ATS is Allan GMC‘s winter addon for Allan’s All-In-One Graphics Fidelity ATS. It is not a standalone graphics pack: it uses the base mod’s skies (version 2.1) and adds winter weather and scenery to American Truck Simulator 1.62.
What it changes
- January-style daylight, cooler and less saturated, with small ambient light, fog and sky brightness tweaks.
- Light snowfall in fair weather and heavier snow in storms.
- Snow and frost on roads, yards and terrain; winter vegetation; snow-covered roofs on houses, shops and industrial buildings, including distant models.
Load order and warnings
The Winter Addon goes above the All-In-One; without the base mod, skies may go missing or turn purple. Enable a single copy of the addon and do not mix it with other winter or weather overhauls, because the effects overlap. Coverage varies by region and third-party maps may use assets it does not cover.
The author maintains it for 1.62 only and will not make a 1.61 version. In the Steam comments several players report game crashes shortly after driving; the author handles support on his Discord, not on Steam. There is an ETS2 version: GMC Graphics Fidelity Winter Addon ETS2.
