the map improves more and more.
+if the rails blocking zeds remove them but dont remove the border on the grait.
+the falling rocks are perfect now.
+the new water is very nice. i like to step into the river to feel the cool, clear water on my feets while the sun is shining on my head. very beautyfull.
little tweaks on the foam:
remove the foam that moves in the direction of the arrows. its not nessesary. all other foam is very realistic.
foam tweak 2:
i suggest slower movement and more opacity. lets say 20 - 30% of full visibility. maybe lower. its still water, moved by the gentle wind that is blowing.
alternative to the foam: little splash emitters where the rocks fall into the water. it doesnt have to be in sync with the falling rocks. if its possible to syc them do it. if not i guess its enough to give them the same timing and fequenc of apearing.
two major downs:
-still no helis visible for client. did u ever played ur map as client on a server? u know my suggestion about that

-server crash on mapchange. thats what maksimus tries to point out.
keep up the good work
