Modding underwater light/clarity

[Dignan]

Does anyone know how to mod the hdr_underwater.cfg file in data\filters\colorcorrection?

I've done some searches and found some old mods that you can't download anymore but still haven't found a solution to this. I use North Atlantic Green 1.1 but am still dissatisfied with the level of clarity and brightness underwater. I play full realism and don't think you should be able to see too much beyond the bow of your uboat through the periscope when submerged.

The parameters in hdr_underwater are below. Anyone have any idea which settings to lower or higher to make the water more cloudy and darker? Especially at night, the water should be almost black.
