Realistic Sub

[Torps]

Hey guys how do you fix/make the sub ride lower in the water? I saw a post on it but there was no info really. And also based on this photograph is there a way to move the conning tower and the deck gun forward aswell for tambor, gar,gato,balao etc classes as well??

I don't know. It looks pretty damn close in those comparison pics. :hmm:

Anyways, I believe it's the sub *.sim files you are looking for. Search under 'draught' in the file. Mini Tweaker tool is needed. You can also use a hex editor. Look under single byte. The number to change is the second slot to the right of the letter 't' in draught. Remember, it's a single byte. Good luck with your mod.

Here's example picture for NSS_Sargo.sim...i increased draught value from 5,061 to 5,471 (5,661 was too much)

Ooops, I guess S3D does work on the sub.sim files. :dead:

[jaketoox]

...btw...could that fr_ratio value mean the balance for the sub...i mean that what i have experienced, when changing draught value, it looks like the tail of the sub runs in correct level, but bow runs a bit too deep...i guess i'm gonna try to change that fr_ratio too and see what will happen....

Thanks I got it! See the 1st post

Just a word of caution, Torps:
Messing with fr_ratio has some side-effects, such as breaking the alignment of the deck gun and other nasty stuff. Don't remember in which thread I saw all this, but it came from Leovampire, and I trust his word. He strongly suggests not to mess with that value.

ETA: Found a similar thread that mentions the drawbacks of messing with fr_ratio here (http://www.subsim.com/radioroom/showthread.php?t=125557).

Wow. Good catch. You really know your stuff. :yep:

I know squat, skipper...I just have a randomly effective memory, which allows me to remember details like the above, and at the same time makes me forget what I had for breakfast! :rotfl:

This is a guess, but I think the fr-ratio is tied to the origin of the polar coordinates used by the operational features of the boat, not the 3D model.

This is not unusual in a sim to have 2, or even 3 models that overlap. For example
1. 3D model
2. Physics model
3. Damage model

Haven't been modding long enough to have even a decent understanding of how all 3 tie together.

Some other things give you wierd results. I was playing with the U/D drag on the surface and increasing the drag caused the bow to start climbing higher in the water as the speed increases.

I have a feeling the dev's haven't touched this boat in the water issue because it will require modifying stuff all over the place.

[AVGWarhawk]

Yeah, Leo had stated something to the effect that if you start switching the value to much the sub will just sink. Apparently a very fine line for sub draft in the water. But, never hurts to take a second look.:yep:

i believe you can easily move the conning tower.
Into the corresponding dat file, simply locate the 3D node of the conning tower and edit XYZ axis. It will be X i believe.

[Torps]

What does the GC Height do anyway?

If you could give me detailed info on how to do this id be more then happy to make changes. I don't think I have the software to edit the x axis unless you can do it in photoschop cs3 extended.

gc_height = Gravity center height from the object's bottom [m]. If 0, then the half of geometric bounding box is taken.

fr_ratio = Gravity center horizontal position [>0] (1=front, 0.5=middle, 0=rear).

[leovampire]

I raised the GC value to make the sub's less stable to get the rocking motion on the ocean which is in the Sub Roll Pitch reflection mod of ROW. Raised them to 3.15 most were way too low and the sub's too stable in ruff waters. With this setting the sub is stable when moving in calm waters 0mps winds aand slowly changes according to sea state change.

As to lowering the surface height I also changed some of the figures in the sub's cfg file's. These are my changes for the Sargo in my game. Of course watch it for the Sugar boats as they can not dive as deep.


[Properties]
PeriscopeDepth=16.7;meters =15.239 50ft scopes are closer to above high waves
SnorkelDepth=15;meters =9.144 30ft for radar depth and radio transmissions also on this one I set the message bar to say radar depth instead of snorkel Depth.
CrashDepth=40;meters =45.719 150ft
MaxDepth=100;meters =91.439 300ft
SurfaceDepth=5.061;meters =5.182 17ft
TorpLaunchMaxDepth=30;meters

Also in the same CFG files if you want the slowest forward and back settings to be Silent running compliant use these settings like I do for my Sargo.

[EngineProperties]
AllStop=0.00
AheadSlow=0.40 =0.20 silent running submerged just under 2knt's
AheadOneThird=0.57 =0.40 I did this for better power curve
AheadStandard=0.80 =0.60 Better fuel consumption vs original telegraph setting
AheadFull=0.94 =0.80 Better power curve
AheadFlank=1.00 =1.00
BackSlow=-0.26 =-0.20 silent running submerged just under 2 knt's
BackStandard=-0.40 =-0.30 Reverse speeds should not be very fast so did the fallowing
BackFull=-0.53 =-0.50
BackEmergency=-0.66 =-0.70 only because back emergency should be pushing reverse to the extream but never as fast as ahead flank.

How you feeling LEO after your operation...I hope all is well with you.

[leovampire]

How you feeling LEO after your operation...I hope all is well with you.

I know they are trying to keep my heart from working hard but the pacemaker is keeping it too low and my body and brain wants more and not getting it so I tire out fast.

Even going for a walk with the dogs wears me out just going around the block. :damn:

I don't like taking pain pills as I like to keep a clear head about me so the new chest cut is bugging the hell out of me.

But I am doing my best to stay :|\\

Ive looked everywere sometimes theres not enough info to determine what I am changing. Any idea which part?

My dad had major heart surgery not long ago, people messing around with your insides takes a while to get over; you'll feel it for months & anything to do with the heart makes you tire out easier, also for months - my father had his operation last year ('06 early spring iirc) & he still has limited energy. It got better after a time frame of about six to eight months but seemed to peak at about 70% of the energy level he had before. If you drink or smoke it can be much worse, he never did either one in his entire life and it still got him down. My sister was an R.N. at the heart hospital here in Arkansas for a while & she told him how it would be & she was almost right on the money.

But some come back to nearly what they were before, I hope you are one of those. Keep up the cardio activities & keep your chin up, atitude has a lot to do with health; never lay down or give up.
