Just ask waht u need to learn and iam sure there is plenty of WO here that can help you.
I started out to look at thos cfg files. Thos are easiest to mod.
Just use notepad but when you change numbers, you sure want to know what the numbers represent.
SH3 editor let you change many variables, and best of all you can add new ones, but its a bit difficult.
example. for sh4 i did a longer wake mode, and as i digged depper into it i figured out how to add more wakes from a ship hull. it was darn time consuming to add them and to get them right and so they lined up whit the others.
But it looked more realistic if i could have 4 wakes to play around whit than just 2 that was normal for most ships/subs. I could make them go into each other. Alter thier angle etc.
As soon u get into the modding thing its not that complicated even if it sounds so.
Darm iam just a lazy swed and even i can do it
