Snow accumulation logic

As per the title, did anyone get the logic beyond snow accumulation over ground aprons/texture?
Is It per color or material?
Or maybe roughness in the comp texture?
E.g. default asphalt i get Little to no snow, however, a lighter apron in the vicinity get full snow coverage as well as all the grass and Buildings
I can live with a logic where black/surfaces Will melt snow faster, but i’m trying to replicate a normal Airport behaviour where snow Is being plowed pretty much everywhere except on the grass
