The last days I have been messing around with some stock particle effects which I thought could be improved...
So I added some things to all player subs:
1. New Bow Spray (which has big particle effect in waves and less particles in calm sea)
2. New Conning Spray
3. New Waterspray for u-boat decks (created by Tomi_99) and conning tower and added to all subs
Have a look:
