playing with unity

as the title suggests I've been playing with unity over the last couple of days and have figured out how to get my map to look as though it is actually underwater. First i used a mat blue skybox for two reasons; it is damn near impossible to find a underwater image that will work as a skybox and because it looks really good how i have it. Next i used basically the same colour fog as the skybox and put it on pretty thick, this dose wonders for the visibility and with the right tinge it works really well.

The next part was a little tricky but i did it and it really makes the map so far. I used a particle emitter on the main camera and set it so the particles just float and i made the ellipsoid longer along the X so that the particles are spawn far in front of the player.I then put a spot light on the main camera to give the added feel of being inside a diving suit. Next I made my own dust spec in photoshop and made a alpha channel so it would appear round in unity and i made the texture for the particles self illuminating so that they are dark when far away but when you get closer they react to the light and light up as they would in real life.

I'm very happy with the result and cant wait to now make the map and model the base and ship and various plants.
