With the winter season starting snow/icing is becoming more and more common but unfortunately,
MSFS doesn’t do a great job at displaying these effects on the ground compared to x-plane12.
Icing in X-Plane12
Icing in MSFS (Non-existant)
Snow in X-Plane12
Snow in MSFS (Looks like the regular rocky ground but painted white. No snow height)
The snow depth slider is not depth related at all but coverage related.
