There is no need for left and right side versions of 140mm cannon

Before export ensure Head pivot point x-axis points in the direction of the gun and z-axis points upwards.
Ensure Gun pivot point x-axis points in direction of gun and y-axis points downwards.

This is the primary reference I use for naval weapons. Here is a link to the page covering IJN 140mm guns.

Main IJN page is here http://www.navweaps.com/Weapons/WNJAP_Main.htm

Info on turret elevation for 140mm guns.

Nagato class:  As built:  -7 / +25.  Later:  -7 / +35 degrees

Hi.

There is no need for left and right side versions of 140mm cannon

At first, I think so, too.
And set overiding  HeadMinYaw,HeadMaxYaw at Nagato's several cannons.
But this overiding is not work well in my IL-2 1946. Only my Nagato (other ships look well working, why?).
140mm cannons rotate into Hull.

At last I scceeded in 140mm cannos rotation limit by name _left_side or _right_side, with no-overiding.

It is a mystery of me.

[asheshouse]

I see your error here, -- from the code in your earlier post

Code: [Select]

HeadMinYaw             -89.0
HeadStdYaw               0.0
HeadMaxYaw               1.0

This setup means that for the left (port) guns they will rotate clockwise 89 deg (into the superstructure)
but only rotate 1 deg anti clockwise. The image shows exactly this happening.

The HeadMinYaw and HeadMaxYaw must be different for the left and right guns.
These entries must be put in the Nagato section of ships.ini so that they are different for the left and right guns. Also each gun location can have adjustments to the firing arc if required.

Look at the text entries for Warspite 6in guns. They are very similar to the Nagato 140mm guns.

Reantal Model IJN BB Beta1 Nagato
https://www.mediafire.com/?nt4l9ouc41ici6d

This needs my old MOD/BETA MOD's class files. only class files pack here.
https://www.mediafire.com/?0ywo2ac21oxc147

Class file "A82C5D9CBD687648" is ShipWes class file. Every my ship MOD's folder has this A82C5D9CBD687648.
If some folder's A82C5D9CBD687648 is old version, error occurs.
Please overwrite A82C5D9CBD687648 to all my MOD folders.

[crazyeddie]

70% ctd in 4.10.1 with SAS Modact 3. Tried both class files.

[asheshouse]

Congratulations on getting the first IJN battleship into the game.
It may be Beta but it still looks great.

Installation was no problem, using HSFX5.
The instructions are clear, except maybe regarding what to do with the class files.
I would suggest that you just include all of the correct class files in the model folder along with the new ones. They are only small files.

crazyeddie -- make sure you did not overwrite the 3 new class files in the model folder with the old ones.
You do need to add the full set of class files to make it work but do not allow the 3 new ones to be overwritten.

[crazyeddie]

Cheers Ashe, will try it again.

[asheshouse]

Just in case, like me, you cannot believe how small Nagato looks next to Akagi, here is a real life photo.

[crazyeddie]

Ref my first post - my misunderstanding of what to do with the class files - Sorted.

My congratulations to Western the builder, and to Ashe and the others for their help and advice as he progressed.

A wonderful bit of co-operation and another fine ship to add to the game.

BZ as we used to say in the RN - You can all take a well deserved "Make and Mend"

[asheshouse]

I think there is a problem with the way you have done the guns.

This is the code you have inserted in ships.ini

The problem is that the Gun Classes
CannonQFMkI_134mm
CannonUS_5_38Mk12
are already used.
I think it may be wrong to define characteristics for these more than once.
Only one set of characteristics will be used by the game engine.

You must either use an existing gun type or define new gun classes, as you have done for the CannonJA_406_Type91

The CannonJA_406_Type91 gun effects seem to be wrong. The gun flash does not align with the barrel and the size of the blast is too small.

You do not need different guns to be defined for the left and right 140mm guns

To start try using the Marat guns [gun_0120_1905]
I used these for the secondary 6in guns on the Warspite.

For the main 406mm guns try starting with [gun_MkVII_356] --- from the KGV Class.

Once it is all working correctly new gun classes can be substituted.

I try and want to ShdwRcv on Nagato deck.
I take ShdwRcv meshes from Akagi, and tweak on MAX, export to .msh, wrote Hier.him ShdwRcv.

But on Nagato,  ShdwRcv looks no-working.
A plane fly over Nagato, its shadow isn't drawn on deck.
More than that I want, Nagato's SST and Stack, cannons shadow drawn on deck.
I see, this "Ship Structure's Shadow" is different from a plane's shadow, at looking at Akagi.

Akagi show me , only planes' shadow on deck by ShdwRcv.
Akagi's SST shadow is drawn on sea, but not on Akagi's deck.
I check this in FMB Date change, AM8:00 or PM4:00 Sun going up or down shadows streched long, but...

Then , like my easy test, if "Ship Structure's Shadow" is outside of ShdwRcv work,
my wish is no way to scceed by ShdwRcv.
Is it true?

Or.... does other way exist in IL-2 1946, "Ship Structure's Shadow" shows on Battleship deck?
