me, too.
no, its hardcoded. spent days on that...managed to have more rough looking smaller waves. but thats all. the foam thing is not reachable, i managed to take a look into the act files and the exe of sh3. i dont remember in which file i found it, but the waves are created due to coding stuff and the foam (which foam texture is used at a certain windspeed) is defined in this file too. so the values exist, ive seen them. but i do not know, how to interpret/change this code stuff.
