It would be cool to be able to determine the sea state independently of the wind strength, because in reality the sea remains rough even if the wind has decreased.
Follow arborescence of the OvGME mod, you'll see where files go (........DCS version\Mods\terrains\Caucasus\vfstextures), OvGME works fine for me for this mod.
Sailing here too, and it was my job for 40 years, I just find for north one yellow is too low from sea level and for south one it's black
Edit: example noth one
Very nice, for the black/yellow buyos, in international code you have yellow/black, yellow/black/yellow, black/yellow/black and black/yellow when you go from top to bottom to make north, east, south and west buyos
