Just put in 3000 3000 and 100 or whatever water depth you want, a standard map is something like 2048 x 2048.
I dont want any cookies, thanks though.
right - standard map goes from -1024,-1024 to 1024,1024 so if you set the water scale to 2048 2048 128, and then set the POSITION to 0 0 0
it should work properly and cover your whole map like you want.
While 3000 3000 may also work, theres been problems when the water scale is not a "power of 2' in all 3 directions.
