Hello, just wondering about environment. When I watch Pictures of the Aircraft it is covered with snow on some Pictures. So I did the recent update and put the A340 Lufthansa atf EDFF, which just closed down due to too much snow. So Question, will the Aircraft be covered with snow after a while, or do I have to push a button to do it myself?

It will dynamically cover but the timing will depend on the ambient temperature and rate of snowfall.
