1.) Yes, it's from latest ROW

2.) Go ahead ;) thanks for asking :up:

Nice mod, but a problem. The porpoise, Sargo, and Tambor, had three bladed props. The four bladed did not come out until the advent of the Gato class. All boats after had the four bladed model. I think the Balao had one step further and some had a strange looking 5 bladed prop. Not sure on, more research needed.

kapitan_zur_see 01-23-08 12:59 PM

interesting...
Tell me if you discover more about it

Any clue about the wrong direction of the propeller rotation? They rotate as moving backward. How can I correct this, kapitan?

:ahoy:"no solutions on sight, Sir !!"

Correct! According to Norman Friedman, author of US Submarines Through 1945: An Illustrated Design History, three bladed props were the norm until Gato-class. I find no mention of five-bladed props for the Balao's. Perhaps this was done after the war? :-?

Cheers! :ping:

nope, sorry :cry:
If i understand correct, it looks like most of my mod is to get rid unless gato class lol
Going back to work on other things for the moment...
:lurk:

Personnally, the idea that 4 bladed props didn't see action before the Gato release isn't bothering me that much.

I love those new propellers, good skin, great textures (compared to the stock 3 blades) and nice motion to watch.

It doesn't bother me either. I did some research and threw my findings out there. Whatever kapitan chooses to do is ok by me...:yep:

I am impatiently waiting on more info on his Narwhal creation! :D

DavyJonesFootlocker 01-23-08 04:09 PM

You da man! Tried it out in TM and it looks spiffy! :up: Like the swirl effects on it too. Gonna use it on RFB and see. Shouldn't make much of a difference. Again nice job!

donut 01-23-08 04:37 PM

Remembering Capt.Cox got stock turning corectly ?
 
Pitch is hard to see. Thought they were turning wrong though !:hmm: If it isn't one thing it's another,:lol:

I'm currently working very hard on it ;)
It got me to learn lots of new things about modelling in 3DSmax. You see, modelling some propellers is one thing, but an entirely new submarine from scratch is very very hard lol It just that i have to practice some more :hmm:
But eventually, i think i'll manage (i hope at least lol)
I do have a kinda nice blueprint with left and top view of a narwhal, but infortunately not front view wich makes things harder.
If anyone has any good pics, blueprints whatever usefull... think about me ;)

Also around 1943-1944 all US Sub types which under went refit, had been upgraded with 4 the blade props :know: .

Capt Jack Harkness 01-27-08 06:17 AM

Not to nitpick, but were the boats' props really that crudded up? And the props are rotating backwards... They are on the right shafts with the right pitches, but the shafts are spinning the wrong way (just like vanilla). Anyways, nice work on the model/texture, hope we can find a proper fix for this problem...

Oh and someone mentioned 5-blade props on some Balaos: The post-war Tench class and some Guppy converted Balaos had 5-bladers, not the wartime boats.

Nice Model!

skwasjer 01-27-08 07:02 AM

To swap the prop direction try swap the x-offset values of the nodes for left and right prop. Iow. you want to move the left prop to the right location, and vice versa. You'd have to change the pitch again as well though (either in 3D suite or you can try rotation -XZ?). This is a bit of a hack, but I haven't investigated if there are other ways to do this... Just an idea ;)

andycaccia 01-27-08 08:13 AM

I guess I could use S3ditor to do that, I could try and see what happens. Confronting stock game sh4 and the 4 blade mod I noticed that the propellers blades had the same direction, while they were inverted in the popular propeller fix mod (later included in some other works)...hope it works.

Thanks skwasjer...from the Olympus...a true Deus Ex Machina...indeed.:up:

andycaccia 01-27-08 08:37 AM

:rock: IT WORKS!!!:rock:

Just swapped the X Offset values in the nodes and now the propellers are fine.:arrgh!:

Excellent idea skwasjer, thank you again.:yep: :up:

Sailor Steve 01-27-08 01:50 PM

A lot of work for something that we'll never see.

External view? What's that?:rotfl:




Aw, who am I kidding? This is great! Thanks for all the trouble, KzS.:rock:

Canonicus 01-27-08 03:19 PM

FYI....Make sure to swap the "XZ" values or the prop shafts wont be seated in there stern tubes correctly. I found this out after making the "X" changes to the Porpoise class subs.

Cheers!

andycaccia 01-27-08 03:39 PM

I tested the Gato class with the X offset inverted and It looks fine. Did not touch anything else at the moment. I will change all subs when I have a free minute (penal law is hard to study:88) )...

Canonicus, are you sure you swapped the right offset values? My changes are OK, on the gato class at least..
