ok, i'll try to explane a little further, the water is in the begginning about 1 meter deep, it is located in the bottom af a big room.
when the player presses a button (which is located just above the water surface) the water starts going up.
now the player has to climb all the way up again before the water reaches him.
when you have finished climbing and the water has gone to its highest point (which is about 1 meter from the place where the player now is) it disappears. so the player is never in the water when the texture disappears, he is e few meters abouve the surface looking down into the water.
as it is now i can se right through to the bottom some 20 meters down..
