Transparent parts invisible underwater

[Festivereinhard2 (Festivereinhard)]

I noticed that when I put a transparent part in the terrain water it become invisible. It doesnt matter what the transparency setting is set at, as long as its not 0.

Maybe it’s easier to render that way?

OR like ice cubes. You know how if you throw an ice cube into water it vanishes? maybe that’s what there going for.
