Last Month the Japanese try to retrive this mod a little bit more. They played in the at 2pm CET. At the moment the gametracker,com Server Monitorring is off. Hope soon they turn it on. The ranking seems to work.
if you use 'lots' of trees' then consider making only the ones close to the road actually have collision mesh.. this will reduce lag.. and also maybe consider making the trees in the 'distance' just cut-out trees.. like the people in the arena bleechers.. they will still look cool at distance but can be made of a UBER simple 'plane' mesh.. if you use those techniques you could really go crazy with the effect of a very dense forest.
