Lo mate!
1. The 16k mod expands your (rendered) view-distance from 8k (stock) to 16k. You and your Crew can now see ships and land from very faaar....so do the Tommies!
The murkier water, is intended since the sub-simmer of GWX believe that one can not see far under water. IT's conected to the GWX mod...in general. Not the 16k mod per se.
But if you have SH3 Commander, you can set a custom value to the underwater murky-ness.
2. as for the glow...i'm not sure! Sorry!:hmm:
