I had the trim problem this morning whilst playing... at periscope depth and the boat would go into crash dive pose. ugh... I know modding is not always easy ;-)

if you search a mod that helps to forget about any realism in diving - thats the mod that does it. VEEERY realistic when uboat falls like rock into the deep without moving. Even changing config does not helps. But i like how uboat changes trim on diving. Well, mod just need to be corrected on more real model of keeping depth. Because with mod turned on you cant even float up WITH BLOWING BALLAST FROM 15 METERS (Das Boot showed that submarine can do it without any speed ON 280 METERS).

Thanks.

my code was tied to depth presets. But I did not take into account that the use of ballast valves also affects the depth change to some extent. It would not be easy to edit it, so I changed the logic in general.

As a result, a bonus will appear in the update: now the boat changes trim not only during crash diving (hooray, there are many more bugs with the boat's trim breaking))), but also during the usual depth change (around 10 degrees, while crash dive is 15-20 degrees)

I really hope that this will solve the problems that have arisen before

I found the reason why the boat starts to trim underwater when it's not expected.
I'll fix it soon

I hope this will finally solve the problems

@Q4ZS your not the only one having that problem

anyone else not having the sub level out underwater now?

wait so is it fixed?

The functionality to hide the depth gauge arrow has been disabled, as it will be used in another mod

@Donny Donowitz the depth is indicated at the bottom of the dial (both during and after depth selection)

but how do i input the depth i want to go?

This is the mod location if you want to edit the config file, in case anyone is interested

I'd like to see a video of this mod in action.
Perhaps the modder could record us something nice and put it on here? :)

I'm volunteering my Save as tribute. No guarantee that I will be able to give reproduction steps if the bug reappears, but I will be trying things on my end to see if I can fix it. Will get to it as soon as I'm finished with my clean reinstall.

I have to have engineer at the depth controls, that stopped the boat sinking for me.

My only issue was that it was too low in the water when periscope depth to use the scopes.

@Xryas Yup, your steps are correct. I encountered this bug yesterday as I had to dive & stop the engines to avoid detection. I let my sink to the ocean floor and saved my game & quit. After some time I loaded my save and I was barely able to get up again as the -20% buoyancy effect stayed active despite running the engines at full power.

Maybe (I don't remember) the DeepLeaks mod caused some additional leakages as I was sinking to the ocean floor, which might affected the overall buoyancy of the boat. But so far the DeepLeaks mod and your mod are working good together (at least in my case).

I was able to get up again and even on the surface I had only 80% buoyancy. I managed to make it to my base and switched my Type VIIC/41 to a Type VIIB and then back to a Type VIIC/41 to fix the buoyancy issue and continue my save.

Either that or perhaps the game didn't recognize my speed and thought I was in "stop mode" which caused it to sink further. I was already cruising at 3knots and accelerating to 7knots didn't help levelling the boat but rather caused it to sink even faster.

Hmm the wrongful trimming happened to me once when I was cruising at 90m of depth. Suddenly without any notice, the boat started trimming downwards and it just kept going. When I passed 120m I became aware of the steep angle and had to emergency blow to not sink. At 20m I set the depth to periscope depth and cancelled the emergency blow. It got my boat to some 10m of depth but at that point it was still trimming downwards seemingly trying to get to some unknown deep depth.

After having separated from the convoy I set the new depth to deck awash and then 50m and that resolved the weird trimming error. (this is the fix I saw mentioned in the comments here last week)

I suspect that there is an error with the depth gauge where it basically skips the visible 0-260m depth arc and somehow understands it as 260m-520m? I'm not really sure though.

@Scarabaeus I tried to reproduce the bug on Type VII and Type II.
The bug didn't work for me.
1) I dived with negative buoyancy;
2) I sank to the ocean floor;
3) I saved (I tried quicksaving and saving in a separate slot);
4) I loaded save;
5) I turned on the electric motors in any of the drive modes.

Buoyancy returned to neutral

Are my steps correct?

Wow I wouldn't have thought of that.

I still fully support this mod and the work done just needs a tweak. Good work and thanks to all modders.

> I'll try to reach a base to fix it

Nope, that doesn't fix it. Switching subs back and forth fixes it. In case you don't have enough blueprints to do so, open the developer console (requires workshop item) and type:

"ShipUpgradePlans 1" -> Gives you 1 Blueprint (!!! WARNING !!! - This will disable achievements)

Then switch the sub to another model. Repeat the process once again.

@Xyras: I encountered the same bug as @Bana. Steps to reproduce:

1) Dive, stop the engines & let the sub sink to the ocean floor (230m in my case, -20% buoyancy was active)
2) Save & reload the game
3) Restart the engines

The -20% buoyancy effect stayed active despite running engines.

This mod ruined my save.. Worked at first but eventually I had the -20% all the time, even with engine running and periscope depth order. I had to egalize during a fight, now I'm stuck with -30 everytime I dive, and +40 when I egalize.. I'll try to reach a base to fix it

Definately needs a tweak. I disabled everything but periscope depth is making it angle down.
It feels like its trying to keep more than 10m under, when it needs to be flat and something like 5m to make the attack scope work.

Do not install. Periscope depth faliure.

@ctbb but the bug appears when i'm at surface and i just hit periscope depth

I don't yet know how to reproduce the boat's trim problem at periscope depth. I tried different cases, but everything is fine with the boat. As soon as I figure out the cause, I'll fix it

Any progress on the boat not bobbing around like a cork in the way that is unbelievbily unrealistic to the point that its incredible the makers didnt instantly say what the hell why is a massively heavy boat bobbing around like a cork in mild seas - thing?

About the dive angle problems at periscope depth..
i found out that if you blow the ballast, then hitting the button periscope tife you will gett the 45+ dive angle.
to prevent this

A. dont blow the ballast if you dont intend to fully surface.
B. if you blow the ballast then after set depth to ca 40-50 then hit deck awash button then after hit periscope tiefe then the boat will level out on an even kiel .
it works for me atleast.

I'm temped to lose a couple months of in progress since this mod has completely broken my game

please fix this bug, the fact that it keeps making periscope useless despite deactivating the mod is unbearable

@Xryas Same error as @Nymbat The Eternal and @FragGPT. I've disabled the mod, loaded into the game, dived, surfaced, unsubed from mod and resubed to download, reactivated, dived, surfaced, and dove again with the same steep downward angle, I wanna say it's like 45°+ dive angle.

@Mr. Silver
I tried around quite a bit with that. Always have a guy at the valves and have 10 crew members with the "crash dive" ability.

Tried the following methods:
- simply pressing crash dive
- first opening the valves then hitting crash dive
- first alarming the crew then pressing crash dive
- after hitting crash dive sending an engineer to the dive planes
- tried different speeds from 0 to flank.
None of that made much difference. The dive times varied a few seconds each time, but always stayed around 35 to 45 seconds.

@Xras I'm having the exact same problem as @FragGPT, and I made for certain that I have the latest version.

@FragGPT do you have the latest version of the mod?

i've a problem with this mod. At periscope depth, even with an officer at depth control and moving, the sub tilts forward, making the use of periscope extremely difficult. Not sure if it's intended.

@Ctbb. Did you also test for the Typ II Boat?

I tested to get the boat to sink in a slower pase and found this number work pretty good

StopMassVII = 10050f;

it makes the boat drop ca 10m in a minute whithout extra help from an officer.
whit help from an officer the boat wont drop at all and have neutral boyancy.
tested whit the VIIc.

Does anyone know what depth the negative buoyancy should take effect "realistically"?

To speed up dive times, create a schedule for the valves. Assign specific sailors to the valves so they're always standing there ready to flood the tanks. You should always create custom schedules for key tasks with hand selected sailors assigned to them. Helps with immersion and
efficiency. Example, I have a cook, 2 valvesmen, 4 Depth steersman, 2 helmsman,
assigned sailors for every officer from the torp mechanic to the captain. I have a 49 man crew and all but 9-10 sailors have specific duties.

@K0T1K Disabling the mod definitely won't fix the problem.

I did this when I had a similar problem (the mod needs to be updated): I was moving to the Atlantic, where the water is deep. I performed an crash dive, waited for the boat to reach the required depth, and then pressed the ascent button. After surfacing, everything returned to normal. If that doesn't help, then we'll need to dig deeper. I think I'll need your save file that has this problem

@Xryas

I’ve already tried that, and it didn’t help me (I don’t know how, but I could send you some screenshots). Also, I want to clarify — I want to delete the mod, and even when I tried to remove it, I still had the problem with the differential. How can I fix this?

@Ctbb. I hadn't thought about this aspect of the issue yet. Uboat has a special instrument located in the control room that shows the boat's trim

@K0T1K I ran the tests and with the mod update this problem should have disappeared. I recommend updating the mod, performing a crash dive, and then surfacing

@Mr.Woof this means the sailors' skills aren't working correctly. This needs to be checked

@Ctbb If you press the Fly Camera key (Default N key on the keyboard), you can fly the came to outside your boat to watch it dive. That's what I've been doing.

can anything be done whit the camera visuals inside the boat.?
you cant realy se the angle of the step dive in FPP.

After downloading the mod, I played with it for 2–3 hours, but because of the immersion issue (when the spoon just stays in place at a depth of 60+ meters), I decided to disable it. After that, I went back into the game and faced a problem: at speed X1 (real time), my submarine at periscope depth or any other depth is tilted at 30–40°. This is very annoying (visually). Sure, it’s playable, but very uncomfortable. Please fix this bug.

I already tried changing the values to 0 in the config myself, but even that didn’t help. I deleted and re-downloaded the mod, but the result is still the same.

@Xyras
Checked the diving times myself. Can't get below 45 seconds for a crash dive even with a fully trained crew and an officer at the dive planes.
Only exception is if I go to decks awash.

Thanks a lot

@JohnMarrington @alexmfishburn updated the mod, the problem should disappear
