there is a new soundfile included in the RealUboat mod
for the crashdive sequence (pressing "C"). It´s taken from the movie"Das Boot".
I think it´s possible to replace the "ship spotted" sound
path: \SilentHunterIII\data\Sound\Speech_En\1-9\WaO_S_Ship_spotted.ogg
with that sound.
Unforunately the game plays the same sound if your watch spotting a vessel in hostile waters or in your own harbour. You would not like to hear that sound played when your watch is spotting the freighter docked peacefully next to you in your home port. :P aalaaaarm...crashdive...lol
For me it´s fine like it is now with realuboat-mod installed to hear that sound after pressing "C" when i feel that my sub is in need for crashdive (Aircraft spotted, destroyer too close to sub
in heavy fog or deep night etc).
If you don´t like to install the real-uboat mod PM me your email, i´ll send it to you. It´s a small file.
Please excuse my horrible english.
