I was playing around with the helos in the open map editor. While trying to hover as close to the water as possible, I dipped into it ever so slightly (just the landing skids) as I accelerated to lift off my vision went completely blurry. It was the effect when you go underwater with no goggles, but as I stated earlier the chopper only dipped the tiniest bit into the water.
I went out into the profile editor and added diving goggles to my character then back into a helo to try again. Same results except the effect on the view was the same as when you wear goggles under water.
This seems to be an unintended effect and I'd like to bring it to the devs' attention.
I'd like to add that the effect turned off when I touched down on the ground. This was rather difficult the first time considering my view was almost completely black.
