There are so many settings of water... Maybe someone know the exact one?

I suggest just messing around with it to see what each one does. Maybe turn the reflectivity down so it's lower than 1? Also, make sure to create a unique form before changing anything! Otherwise you will alter every single instance of that water in the game.
Also, very creative on making that tunnel! I have to learn all the kit pieces (I had
every single one of the, like, 500,000 from Fallout 3 and NV memorized... Now I get to start over

) so I can get creative like that too.
