Yesterday I synced the vehicle damage model for vehicles. This includes doors, panels, lights and tyres. It basically means that a damaged vehicle will look the same for all players in the server, even if you leave a vehicle somewhere in the server, disconnect and join two hours later (assuming no vehicle respawn set). This ofcourse includes popped tyres and broken tail-lights.
I think this adds a nice feeling to the game of things being synced down to the tiny details and it only took a few hours to implement. Stay tuned for more updates soon!
Cheers .
