I have tried the options on the wiki and various other places for a good water shader and a grass replicator. Nothing is really what i am looking for.

What I am using now is merely a reflective surface with some waves. Not quite the water I was looking for.

I would rather have something more realistic like a blue water semi-transparent with reflections. Can someone point me in the right direction?

Also I am looking for a grass and/or tree replicator. For the trees I am using models not sprites. The grass might be better as billboards or sprites but either way is fine.

Thanks for any help.
