OK,
I followed as follows:
Open Goblin app:
In Goblin top menu:
file-open-select "NSS-Uboat7c.GR2", wait a bit...
file-merge- select "NSS_7c.ZON"
file merge- select "NSS_7c.SIM"
In the Goblin Editor:
Double left clic ColisionableObject NSS 7c opens edit field
Single left clic in that opens right Hand field, Change "CrashDepth" value (300m) and Close window.
Now the ZON entries became red.
Did in the ZON the same as before, but new value of 300m was automatically there.
Goblin main: file-save (turns red into black again)
Exit Goblin...
Enter CFG file with Notebook, then:
[Properties]
PeriscopeDepth=12.0
SnorkelDepth=14.0
CrashDepth=300
MaxDepth=500
DiveDepth=35
SurfaceDepth=5
TorpLaunchMaxDepth=20;meters
StormConditions=11,0.4;max wind speed [m/s], max rain intensity [0,1]
I indeed can dive beyond 300m. However Sub is lost because in Zentrale damage area "pressure hull" starts losing Points (from passing 204m on) till it is destroyed. It keeps sinking till "hull integrety" is also "0".
So the cause of death is passing 204m really. (unless immediate surfacing is done. Then even Zentrale press hull can be repaired.)
This I think matches your description with the remark that only TDW might shed some light on this...
If I could delay the "decay" of the press hull to say 290m I probably would get it done.
You mentioned the ZON files of the Systems, but so far I have not found the pressure hull "decay"depth yet...
This:
Regarding the problem with hull collapsing way before the set crash depth is reached, I doubt this is due to any mistake you might have done while tweaking the relevant settings. In my opinion, the point is that as I had written in a previous post, those settings are applied in an odd way that I don't fully understand. The one person that can shed some light on the topic is probably TDW
