try it ASAP

here's the result: water become a wall!!!
that's what I was mean because of the use of a flat map without water. Looks like wall possibly inherited properties of water, and water textures too.
and what about trees in perfect mode? When i turn it off, there is a brown stripe apperar below a horizon line.

I mentioned the snow with the thought that a winter map may make a better base for the mod, but use your green texture.

I got a black wall on the water with sands of time too
