A question about DC UDF's (and some more).

[CBDR]

I think the problem with NTBAriete is that the JRF file does not have any nodes for depth charge racks or depth charge throwers. You would see an entry such as

Node = DC1

or

Node = DCT1

if NTBAriete's JRF model has depth charge racks and/or throwers. Maybe some of the hex editing wizards out there can tell you if it's possible to add these nodes; I certainly don't know how. The node appears to contain information such as type (main gun, secondary gun, torpedo, etc.), location and number of barrels/launchers. If the node is not in the JRF, you can not force it by including it in the *.udf file.

You can modify nodes that exist. For example, you can change NTBAriete's Main1 and Main2 nodes to mount the Bismarck's 380 mm guns, as follows:

[WEAPON1]
Type = TURRET
Node = Main1
System = Gun380mm ;was Gun100mm
ElevRange = 0,85
TravRange1 = 0,-120,120
AmmoType1 = Gun380mmAP ;was Gun100mmHE
MagazineCount1 = 150
;AmmoType2 = Gun100mmAA
;MagazineCount2 = 0
;AmmoType3 = GunGenStar
;MagazineCount3 = 50

[WEAPON3]
Type = TURRET
Node = Main2
System = Gun380mm ;was Gun100mm
ElevRange = 0,85
TravRange1 = -180,-60,60
AmmoType1 = Gun380mmAP ;was Gun100mmHE
MagazineCount1 = 150
;AmmoType2 = Gun100mmAA
;MagazineCount2 = 0
;AmmoType3 = GunGenStar
;MagazineCount3 = 50

Yes, it is a bit absurd (but fun!) to mount such large weapons on an 850 ton hull, but the simulation does not simulate center of gravity, stability and the like, so you can mount whatever turret type weapon you want. Just make sure the *.udf file entry for AmmoType matches the *.ddf entry for AmmoType.

Best of Luck!
