Hi h.sie and all,
it seems that the usage of compressed air after ordering crash dive is actually modeled in SH3
It seems the devs included this!
Just dive and blow ballast so that your compressed air is reduced a bit (you have more than the dial shows. So, with a full compressed air tank you do not see if a small amount is used). Now when the dial is not max. order a crash dive and watch the compressed air dial. Close to the final depth, the dial moves
So, it seems the three main sources for compressed air usage are indeed modeled in SH3: blow ballast, complete surface, and after a crash dive
It seems the devs did things better than we (at least me) thought in the beginning
And the best thing: If you order a new depth before you level out, no compressed air is used, but you suffer from the crash dive blues in NYGM,...
It seems everything fits perfectly. Untertriebszelle is indeed modeled!
