Actually...Fleetboats prior to WWII had three bladed props....they were replaced because four bladed props ,with a different pitch, were more efficient at cruising speeds ,presumably.

So..it's actually not so bad an oversight....

Turning in the wrong direction?.....thats really a "rivet-counter" problem and doesn't detract from game-play in the least.

When they start up they're rotating in the direction that should propel the sub backwards. If you run at 1/3 or less it's very apparent. Actually I'm not sure if it's that they're rotating in the wrong direction or whether it's that the propeller 3D model is made wrong - i.e. with the prop blades back-to-front.

Sadly the closest I can get to a 3D mesh propeller is to make it out of chicken wire and papier mache, and I wouldn't know in which of the computer's orifices to try to insert it in order to get it in the game.

Maybe someone else can have a go? I'll pay well... in compliments! :D

It's simply ...
You can to invert X coordinate by HexEditor in "vertex data" section of propeller Type 1 chunk in submarine.dat ...
OR
1) Extract propeller by Pack3D
2) To invert X coordinate of propeller in 3DS Max
3) Import propeller.obj by Pack3D into temp-file submarine.dat
and than
4) by HexEditor copy/paste "vertex data" from temp-file into work submarine.dat

Hmm.

Firstly, after a search it seems there is no such file as submarine.dat.

Secondly the individual submarines' *.dat files don't seem to contain the words 'vertex' or 'type', and the three examples of 'propeller' don't seem to have anything to do with an 'X' coordinate.

And I have no way to edit 3DS Max files.

I'm 100% for making a change that gets the props working properly and I'm pretty bright but I am no good at understanding machine code. If you know where the data is to fix the props, please just tell us and save us all some time. This cryptic crap is intensely frustrating. I didn't like it when DTB used to do it with SH3 and I like it even less two years later.

Yes, a "clinical" case ...
:rock:

[Fearless]

Yep, as long as the boat moves, I don't care which way the screws turn :lol:

[CaptainCox]

Just had a quick look as i was fiddling with 3DS MAX anyway.
http://i10.photobucket.com/albums/a138/CaptainCox/prop.jpg

What are we talking about here, the actual rotation direction or only the orientation of the blades?

I am yet to find the actual animation file for this but I could have a look later.

[Fearless]

Interesting because the way the blade orientation is shown, the screws should be rotating anti-clockwise.

[CaptainCox]

Hm...I can't seem to pinpoint the actual "animation" file/code for this...might look some more later.

[Beery]

What are we talking about here, the actual rotation direction or only the orientation of the blades?

Each of the props spin in a different direction so I'm assuming that since there's only one prop model it's mirrored on one side or the other. The problem is either that the blades are rotating in the wrong direction or that the blades are oriented wrongly. I have no idea which it is. I'll look at some photos of real subs today and see if I can pin it down. However, as far as I'm concerned right now the main thing is making the props look as if they're pushing water in the right direction. However, when I learn the truth I'll probably be gung-ho about getting it perfectly right.

[CaptainCox]

Well ;) If i can, and i am trying here (HARD!) I could give it my best shot when you find the info. Still fighting with the interface here in 3DS MAX...baby steps. . . .

Or if DD or any of the other 3D modeling guys here might try to give it a shot, whichever.

Suggestion: Hex edit the submarines or the propellers to put the starbord one in backbord, and vice versa:hmm:

[Beery]

Okay I looked at some pictures of Gato submarine propellers. The props in the game are correctly modelled (well... insofar as the props are modelled to push the water the right way). But they rotate the wrong way. So for the most accurate results the goal will be to make them rotate the other way.

[CaptainCox]

Hm, ok...I might have a go at it (no promises that I can make it as I am still learning this stuff) If no one else beats me to it, which is more likely :p

[kakemann]

Never thought of that :oops:

You speak, that a design of propellers blades are correct.
I have correctly understood.???
:roll:

[CaptainCox]

Hi 8BALL, just to get it straight. So the screws in the game rotates the right way?

[Anvart]

OK gentleman
If per chance you are talking about the rotation of the port screw and the starboard screw.
The reason is the starboard screw rotates right-handed and port screw rotates left-handed therefore rotation is correct.

In the Navy I ran the L. C. M. which had twins screws.
one with the left-hand rotation and one with the right hand rotation.
The reason for left and right hand rotation is so that a trim rudder was not necessary. I hope this explains the problem.:rock: :rock: :rock: :rock:
Look propellers ...
and rotating ...

[Beery]

That's correct.
If you look at a any merchant ship or destroyer or any one of the ships with twin screws you will see one rotating in one direction and the other in the opposite direction.

In reality if you take and put two right hand rotating screws on a destroyer without a rudder it would go in a circle. But if you change one screw to a left hand rotation the ship would go more in a straight line.

I think you're missing the point. Certainly the screws should rotate in opposite directions. The port screw should rotate counter-clockwise while the starboard one should rotate clockwise. They don't do that, but the opposite-handed rotation isn't the issue. The point is that the propellers are rotating the wrong way to propel the ship forwards - when you set Ahead 1/3 the screws rotate so as to push the boat in reverse, yet the boat goes forward.

[DivingDuck]

Moin,

which subs are affected? Is it the GATO only?

DD

[CaptainCox]

I think its all of them...have not checked but I am pretty sure. Was looking yesterday between trying to fix that texture, but could not find a animation node for the props.

[Jace11]

If your after any more exercises in 3D modelling / animation, the Akitsu Rudder rotates around the wrong center. The rudder at the stern, rotates around the center of the boat, that's why it has been seen floating on its own off to port and starboard when the Akitsu turns.

This should be a simple fix I think, moving the center of rotation to the rudder's hinge point. Away from the center of the ship.

I would try a fix myself, but while I can open models in Wings, I could only move the rudder to the center of the boat, so it didn't appear. I didn't know how to find or fix the point of rotation.

Where are the animation nodes... etc for things that rotate? One person who would know is the guy that made the radars rotate for GWX.

This is a bit off-topic, but the rotation thing seems to be my problem too.

[Anvart]

For the decision of a problem I (for a long time) simply have changed places the right and left propellers and have renamed them (sub's Tambor, S-18, Balao and Gato):
SubPropellers.7z on my FileFront page (SH4 folder) ...
:rock:

After change:

P.S. Sorry for delay ...

after you have moved the rudders pivot to the hinges, you have to adjust the Z-value to make it appear at the correct position. The Z value moves the object along the longitudinal axis. No need to hex edit anything about the rotation.

The problem with swapping the propellers is that, although they'll look as if they're spinning correctly in terms of the physics, they'll still be rotating the wrong way in terms of the way the real propeller was designed. I guess it's a good fix for those who don't care about such things though. The problem for me is that (as I suspected would happen) now that I know, I care.

If you wish to change only a direction of rotation only, ... rename propellers (_R -->_L; _L --> _R) ...

The problem is, they need to be rotating in the opposite direction. I.e. the port propeller needs to rotate anticlockwise and the starboard one should rotate clockwise. Your fix makes the props physically correct but in terms of historical accuracy it's wrong.

[Beery]

If you wish to change only a direction of rotation only, ... rename propellers (_R -->_L; _L --> _R) ...


It doesn't work. I just tried it. The direction of rotation is exactly the same - the boat moves forward while the props rotate in a direction that should push the boat backwards.

Just to be clear: the problem is not that the props are in the wrong place. They are in exactly the right place and they are modelled correctly in terms of the blades' orientation. They just rotate in the wrong direction.

I'll try it again, but I just tried it not half an hour ago. I guess it's possible I renamed the same prop twice.

GoodLuck ...

[Beery]

I tested again - tried it both ways:

1st test: 1st prop in file named 'L', second named 'R' (default) - port prop spins clockwise (incorrect) starboard prop spins anticlockwise (incorrect). When 1/3rd speed ahead is selected both props are pushing water towards the bow yet the boat is moving forwards.

2nd test: 1st prop in file renamed 'R', second renamed 'L' - port prop spins clockwise (incorrect) starboard prop spins anticlockwise (incorrect). When 1/3rd speed ahead is selected both props are pushing water towards the bow yet the boat is moving forwards.

In other words changing the prop names makes absolutely no difference to the direction of rotation.

Which begs the question - what if we just move each prop to the other side. Maybe that will do the trick. I'll try that.

[Beery]

I tested by simply moving the props without renaming them. As I suspected, moving the props WITHOUT renaming them achieves the same result we get by moving them AND renaming them. The rotation direction seems to be related to 'where' the props are located rather than what they are called.

[GSpector]

Any chance this whole issue is due to Frame rate?

Have you ever noticed the rims on cars appear to go backwards when the car is traveling at a certain speed? Your eyes process images at around 24-32 frames per sec. Your graphic card may be doing the same thing.

Has anyone been able to test this?

It's definitely not a framerate issue. I've set the speed to 1/2 a knot and the props rotate very slowly - easily slow enough to see which way they're actually rotating.

Yes, propellers renaming, does not give any effect ...

It works, it fixes the biggest problem (the fact that SH4's propellers break Newton's third law of motion), but it's still not the perfect solution, since the real submarine propellers rotate in the opposite direction to the ones in your mod.

Captain.....FYI

Prior to WWII, most fleetboats, at least the larger ones, had 3 bladed props.
The change was made to a 4 bladed design that had a more efficient pitch, presumably, to give greater range, although speeds were reduced slightly.

Cheers!

True, but my question was if privateers tweak actually make the screws turn the right way and at the same time corrects the facing of the blades. I believe your mod just switches the position, but the blades are still facing the wrong way...or?

Cheers for that info Canonicus.

[BlightLightning]

Hey,
You know the recomended system requirements are Pentium 4 3Ghz and Ati 9600 - Radeon 8000 or better for the better effects. The Propellers appear to be spinning backward because the high-speed graphic is not keeping time with the system, or so I think. I have the same problem. I tried to get a video card but the newer graphic cards aren't available here in Alaska yet. I am using Radeon G-Force 6200 I just purchased and it isn't fast enough.

No, I believe the problem is in the system. The graphics are there, but my computer is just to slow to keep up with them !!

I have a good setup by today's standards and I just upgraded my video card a couple of months ago. The props still spin backwards, and it's not a graphics issue because I can slow the sub down to a half a knot and they go around r-e-a-l-l-y s-l-o-w-l-y.

Just look up "Gato propeller image" on Google. One's bound to show up. I did my research last week and at the time I didn't post pictures because they're readily available online and I didn't think anyone would care enough to require proof, LOL.

Osprey's US Submarines 1941-45 has a picture of a Gato class sub with a 4-blade propeller that shows that the starboard prop rotates clockwise - it's on page 36.

Here's an image of a Gato model that shows the detail pretty clearly:

Look, the proof is out there. Find it or don't. I don't care. But don't accuse me of hypocrisy when you're posting a photo of a Russian sub's props as if that's evidence of an American sub's props. It isn't.

And I am not your errand boy. If you want to find out what a US sub's props look like, go and find out - do your own research. The problem is, you don't seem to want to. You want me to do it for you, and if I refuse to do it you call me names. I don't have time to be at your beckon call, surfing the internet for you, searching for a sub whose propellers turn the way you prefer them to, and I don't have the patience to sit here while you find ways to let me know that you don't llike me very much.

All I care about here is making (and finding) good mods so that my copy of SH4 is more realistic.

The Gato propellers turn the way they do because some designer made them that way. The fact that you don't like that fact is completely irrelevant, and it has nothing whatsoever to do with me.

Hell, I've said TWICE that your mod is a good fix for the physics issue. But the fact is, your mod doesn't fix the real problem, which is that the props revolve in the wrong direction. The fact that your mod doesn't fix that aspect of the props should not be my fault. It should not end in accusations of hypocrisy directed at me, and the fact that it apparently does says more about your character than it does about mine. If you can't take constructive criticism maybe you shouldn't be making mods in the first place.

Now this thread is called "The props spin in the wrong direction". Why is it that people seem to need to launch into character assassination whenever someone disagrees with them on TRULY inconsequential matters? These are matters that should be merely of academic interest, and hardly something to fight over. I mean what is wrong with some folks? Anyway, let's get back on topic, shall we?

[GSpector]

Hello All,

I was just wondering what would happen if the commands to go forward and reverse could be switched with the Blades rotation. I am guessing this is hard coded.

If not, where is the file that controls the direction and rotation speed based on the command given. I would think if this could be re-maped, it should fix the problem.

Dear CapCox.
In mine mod I only have changed position of propellers that the direction of the screw blades corresponded to a direction of rotation ... ONLY ...
Because at the current moment nobody can't to change a direction of propellers rotation ... (Excepting developers...)...

Actually, it was more for changing the rotation not the direction due to speed.

There are 2 things in play with the rotation when you tell the Sub to go forward. 1st it needs to know what speed to move the sub forward. 2nd it needs to know what speed and direction of prop rotation to correspond with your request.

What you were doing I think was affecting just the 1st part. The second part may be hard coded.

There should be some way to get the Sub to move forwards and backwards with no Prob rotation. If this can be figured out, then I am sure the Prop rotation problem can be fixed.

Okay, the problem is that the standard game's props spin in the wrong direction. But there's another problem - because they spin in the WRONG direction and because the blades are aligned CORRECTLY for the CORRECT SPIN they actually spin in a way such that they disobey Newton's third law of motion - they push water forwards and the boat moves forwards, which is physically impossible. What the fixes do is fix this second problem by making the blade orientations suit the direction of spin, but they don't fix the first problem. The blades still spin in the wrong direction.

[CaptainCox]

Absolutely clear now Beery, cheers!. Well I am back in front of the ol digital box here after a days work so I will look in to this some more, crap...and double crap, must, be a way...must be.

[VonBlade]

Lmfao. I thought I understood it until Beerys clarification has confused me.

So the props spin the wrong way, but are aligned the right way, but push water the wrong way. Or something.

Glad you two are professionals, I'd have got lost at "the problem is" :know:

Naaa. Its very simple...well sort a...na, it is simple.

In this tweakfile I added a new function called (Propellers/ Screws"ENGINE RPM")
Simply put in the "Minus Value" to whats in there now.
Example:
IS "128" (Screws rotate wrong direction)
CHANGE TO "-128" (Screws....ROTATE THE RIGHT DIRECTION! WOOPIE!!"

I only provided the GATO for now...for testing purposes.

Well DL that file and do the tweak and tell me if the screws rotate "LEFT Anti clock wise" and "RIGHT Clock wise"

They should, or I eat my US NAVY OFFICER HAT!
But only the GATO, remember!

Cheers man!

Captain....propeller rotation test completed....

Propellers do indeed rotate in the correct direction...however...
I get no forward movement...none.:down:

She just sits there....:damn:

Yup, full speed but she just sits there. DAM, I have to eat that hat now :o
Cheers man...I think...I think I will look some more in that file and...well, we will see.

Has anyone looked at the animation end of this in Library?

The other thing to consider in setting the way the props turn is the angle the blades are set to grab at the water.

"A right-handed propeller (which rotates clockwise when in forward gear)"

Okay I actualy talked to and got John Hopkins University's Physics Department to check on this for us all. Talked to them on the phone and they told me to send them an e-mail to their department and I will have a reply in a day or 2 or so I was told. We will know the actual rotation of the screws/Propellers on the subs.

[Canonicus]

I believe...I believe.... Just gota believe!..... your getting VERY close to the solution, CC :up:

I don't know if this means anything, but I've been using Anvarts prop mod that orientates the blades for the wrong rotation direction....

Maybe going back to the stock blades may do something. :hmm:

[GSpector]

Looks to me like you guys might be on the right direction to fixing this problem.:up:

As I stated before, there has to be a way to separate the forward / reverse speed from the prop rotation. When you guys can do that, you can get the sub to move forward/reverse without prop rotation or have prop rotation in either direction without sub movement.

Once you can control each independently, you can set each to work the correct way.

[CaptainCox]

Hmmm, yea...well those animation files are for the torp hatches and the torps.
Gonna fiddle some more...bed time soon, but the weekend is coming up fast ;)

Well, that will not fix the rotation unfortunately. I know this is rivet counting of the 5th degree here, but its a good challenge :p

[Canonicus]

CC..did you happen to notice that in the Diesel Propulsion catagory there's an Engine RPM listing that also reads a negative number...same as the prop listing.

The two are connected, because when you change one, it changes the other.

Could the negative RPM number in the Diesel Propulsion catagory somehow be telling the sub that the engine has NO power to move the sub forward?

Or...that , being its a negative number,..... only has power to move in reverse? (which the sub does)

just a thought.

[CaptainCox]

You know...was just looking at that when i peeped in here to look :p
I think it will be the same but when you are submerged... or?
Lets try it out, only way hey!

Ignore the submerged bit, I will simply try it out. Good thinking!

EDIT:Hm...well the Prop RPM holds 128, the E-propulsion RPM holds 127...
I think its is simply the Electric Engines RPM when submerged. But I give it a go all the same.

[CaptainCox]

Ok just last report on this and then I am gonna turn in. Its strange...
setting the Prop RPM to a negative value will turn the screws in the RIGHT direction, but no propulsion forward, BUT! as Canonicus said, it does work when going reverse speed, still using the NEGATIVE VALUE!...WHY????

I also set the E-Engines RPM to a negative value and that simply does not work.
When setting the boat in reverse the screws just stops, but setting to ahead speed, they spin (IN THE RIGHT DIRECTION) but again, no propulsion forward. I am gonna leave it at that for now. I hope some of you guys try this some more...looks sorta promising, but then again it could be a total pointless exercise and it is hard coded after all...but that's Modding ;)

Looks to me like you guys might be on the right direction to fixing this problem.:up:

I think...yes if we could do that we would have cracked this once and for all...but where is that separation, or rather what would that "movement" be called in a .sim .dat etc etc...cool problem to solve all the same.

setting the Prop RPM to a negative value will turn the screws in the RIGHT direction, but no propulsion forward, BUT! as Canonicus said, it does work when going reverse speed, still using the NEGATIVE VALUE!...WHY????...

Okay, what if, as well as changing the rotation to -128 we also change all the engine speeds to negatives in the NSS_Gato.cfg file (all the positives to negatives and all the negatives to positives). That might just do the trick.

On second thought, if the boat goes backwards when using backwards propulsion it probably won't work - but it might be worth a try.

We're most of the way there. I can't believe CaptainCox found out how to rotate the props the other way - it's brilliant!

Whil you guys are at it, someone posted this.

Yeah, but that requires changing the 3D propeller model. It can be done, but it's gonna need someone with 3DS Max skill.

[DivingDuck]

Moin,

Yeah, but that requires changing the 3D propeller model. It can be done, but it's gonna need someone with 3DS Max skill.
it´s not the 3d skills that detain us from making any changes to the models, it´s an issue of TMAP. That´s information that can´t be carried from any 3d programm to the *.dat files using the *.obj file format and Pack3D.

As for the props. They do spin in the correct direction in the physical way. Here´s the proof:

ship propeller 6.4MB MPEG (http://www.cfx-berlin.de/de/anwendungen/turbo/img/propeller.mpg)
ship propeller 600KB MPEG (http://www.cfx-berlin.de/de/anwendungen/turbo/img/propeller_small.mpg)

If they rotate the other way round on the real sub, the props have to be switched as well to make the pitch match the movement.

Regards,
DD

[GSpector]

Nice video.


Canonicus, since you changed the Positive numbers to negative, is there a chance that you have no forward movement because you have 2 screws, not 1. Is there a separate file for each?

[Canonicus]

Well ...I only saw the one engine rpm lisiting in the Diesel propulsion catagory. I would assume that its for both props. I don't see how you would disconnect the starboard from the port, at least not in MiniTweaker.


I was just speculating that the negative value that CC inputed into his Prop & Screw catagory (which is also refected in the Diesel Propulsion catagory),may somehow be telling the sub to not move forward. (You know...negative value = negative movement.

I think you've somehow got to seperate the engine commands from the actual prop rotation as you mention a few posts back. i think thats were the solution may be.

[CaptainCox]

There are some anomalies that we should consider here.
1. Why does the sub not move forward but move backwards when setting the value to minus!
2. Why are there no "bubbles" coming from the screws when setting the value to minus (though we have backward movement)


Whil you guys are at it, someone posted this.

http://www.subsim.com/radioroom/showpost.php?p=551934&postcount=23

Basically means that the number of blades per prop. on Gato and later classes are apparently wrong. Cool info, THANKS!. Problem is we can have only one screw for each sub, so the early/late version will never work...at least not any way i know of. But sure 4 or 5 blades could be added.

PS:Is Subsim just loading slow for me or is it all over?

[leovampire]

The Starboard propeller turned in a clockwise rotation:


http://static.filefront.com/images/personal/l/leovampire/93141/leizlzhwwf.thumb250.jpg (http://gallery.filefront.com/leovampire//590987/)



and the port side propeller turned in a
counter clockwise rotation:

http://static.filefront.com/images/personal/l/leovampire/93141/chblrdvzog.thumb250.jpg (http://gallery.filefront.com/leovampire//590989/)

They said the reason for this was to reduce the cavitation effect
to help keep the noise leavels down and to reduce cavitation
damage to the blades wich was a common occurance. If the damage
was bad enough they would actualy change the props when the sub was
in from a patrol. the reason for the odd number of blades was that less turbulance
was created by odd numbers.

These were the example pictures they showed me in the e-mail for angle of
the blades. they stated they were just examples.

[bigboywooly]

Yeah you can import 4 bladed props

[leovampire]

Definatly shows how the blades should be for the rotation to pull the water past the boat.

[Beery]

As for the props. They do spin in the correct direction in the physical way.

I've always said that they do in the mods. The problem is not the physics - we have a solution for that (two of them in fact). The problem is the rotation - WWII US sub props rotated clockwise on the starboard side and anticlockwise on the port side..

[Beery]

Perhaps there's another angle from which to look at this. If we can just find the data that the speeds in the sub config files alters we might be able to crack this from there. I just altered all the speeds in the cfg for the Gato (minus to plus, plus to minus) and the props rotated properly when I set forward speeds, but the sub, of course, went backwards. If we could find a way to make the sub go forwards when the cfg file tells it to go backwards (and vice versa) that will solve the problem.

[CaptainCox]

I will join in with the rivet counting today as well. Gonna have some late lunch and start fresh :p

[CaptainCox]

Ok had another go at this...so far I only could get the "voices" say "Full Speed ahead, but the boat goes back and vise versa. Did this by changing both the Max Speed and the Electric Max Speed + the Knots etc to a negative value.
