Simulate Under Water.

Ok so the majority of my game takes place under water. i’d like it to be a royal blue but transulcent so you can see the player (its in a third person perspective) any idea on how i could do this?

I’d point you to watch “How did they do that? - Mario Sunshine’s Water” from ClassicGamejunkie
it briefly mentions what techniques the game used to make great looking water that’s easy on the system. from there you can go into some research over which techniques that you want to use for your game and how you can do them.
