I improved the Mod Snow v2.0 from the modders "Jumbo0: gr8man: Jantsu92: Alisa Bellucci: Flash" thanks to them that this Mod exists on GTA IV now when you roll the tires of the car leaves traces on the road and especially no green grass as was the case in the old version of the mod, it's all snow and also when walking with Niko Bellic these shoes leave traces in the snow like in GTA V.
