After some thinking I'll revert things to like they were originally :-). I can't change base noise level without changing resulting max cavitating NL, so I can't increase speed added noise because I would increase torpedo NL overall, decreasing possibility to make them stealthy. Even though difference between slow and fast torpedo would be greater, the actual noise level of slow torp would be greater too.
So I'll revert it to stock game settings, can't find anything better for now. Database NL back to around 82, speed noise +10, only changes left in mod would be that big or thermal torps would be somewhat more noisy than small or electric ones.
edit: I'm confused now because I noticed that torpedo base NLs in the mod were reduced not by 10, but by 20 ! So reverting them to original would mean increase them by 20, huge difference. Maybe first I should add 10 and see if it's enaugh ? :hmm: Don't know to do now, to be honest... Maybe I should make two versions and send them to you Molon Labe for betatest ?
Was it possible to send a "stealthy" (slower, non-cavitating) torpedo in stock game ? Don't think NL around 85 is much stealthy...
And is it possible in real life at all ? For example ADCAP is very noisy torp and not much stealthy even at 40kts...
