Volume Fog

Is there any way to enable this or achieve the effect with material tweaking. I need to create a realistic underwater scene and that is not easy without volume fog.

just as an advice, you can easily make you r underwater scene using a zdepth of the scene, and use it as color correction in the most primitive way to do it, or use it as feed for fog effect in compositing software. best luck!
