Vehicles/VehicleScripts/NetworkEvents/SnowSystemEvents.lua

This file contains all event that are relevant for the snow system, in particular those parts used in SnowBlade, SnowCannon, SnowDisplacement and SnowGroomer.
Note that all of these events are server→client only, i.e. only the server is authorized to trigger changes in the snow system for each client.
