Also the 3D for the Scufundare vapor.wav, with this ticked the sound is only whispered! The files have a long period of silence to help in stopping the sound from looping, funny but having the loop ticked is better, also with it unticked as long as you are in the area between 20m to 800m the file loops, I have tried a number of time and it
seems the looping has gone!
Anyway like I said it's about the best I can get it!
Edit: Additionally the hyd sound is still set at 1100m, one of the main reasons for shortening the audible sound to 800m was so that you clear the zone quicker so as the chance of looping is minimal or gone.
