Porpoise Conning Tower Upgrade...
 

I just finished a mission and they gave my boat the half-cut conning tower upgrade. So i had to add the radar again but on the next mission the radar didn't work. It was shown as being equiped, but i could not turn it on and the scopes stayed dark.

So i started digging into the files and i noticed that in the Unitparts2Porpoise.upc file under UPCDATA/UPCUnitsdata these sections...

For Early War Tower,

[UnitPart 1.Compartment 1.EquipmentSlot 1]
ID= SurfRadarAntenna
NameDisplayable= Surface Radar Antenna
Type=NULL
AcceptedTypes= NULL
UserCustomizable=Yes
IDLinkEquipmentIntervalDefault1= NULL, NULL, NULL
ExternalNodeName3D= R04
ExternalDamageZoneTypeID3D= -1

For Half-Cut Tower,

[UnitPart 2.Compartment 1.EquipmentSlot 1]
ID= SurfRadarAntennaLate
NameDisplayable= Surface Radar Antenna
Type=NULL
AcceptedTypes= NULL
UserCustomizable=Yes
IDLinkEquipmentIntervalDefault1= NULL, NULL, NULL
ExternalNodeName3D= R01
ExternalDamageZoneTypeID3D= -1

For Late War Tower,

[UnitPart 3.Compartment 1.EquipmentSlot 1]
ID= SurfRadarAntennaLate
NameDisplayable= Surface Radar Antenna
Type=NULL
AcceptedTypes= NULL
UserCustomizable=Yes
IDLinkEquipmentIntervalDefault1= NULL, NULL, NULL
ExternalNodeName3D= R01
ExternalDamageZoneTypeID3D= -1

Note the ExternalNodeName3D= entry, it starts as R04 then changes to R01. So i edited it to say R04 and reloaded the game from a save before docking and the radar worked on my next patrol.

Was this just a Typo by ubisoft or do i have a bigger problem i need to track down? I noticed that some boats like the Gato use R01 for all 3 entries, but the Salmon and Sargo also go from R04 to R01 like the Porpoise, could this be an issue for those boats as well?

Any insight would be welcome, Thanks!

The R01 and R04 are only the nodes for the postion of the Radar on the submarine. Usually the reason they change is because the radar changes and it can no longer be mounted at the same location.
You said the Gato uses the same R01, so that means as the radars change they can still be mounted in the same location (the R01 node), but in the case of the Porpoise, the radar changes, but possibly because of the cut down tower, it can no longer be mounted in the same location, so the node has to change.
If you use Silent 3Ditor (S3D) and go to the library/USSubparts/Sensors_sub_US.dat and open the preview window you will see the different types. Some are just on poles and some have brackets attached. So that is the most likely reason for the R01 and R04 change, it is changing the location the radar is mounted.
As for the radar quitting on you, it is possible that after the tower is cut down, you may have to purchase it again. I am not sure why that happened.

Here is the P_01 tower showing the R04 node and the radar would follow the blue line pointed to at the top of the picture and most likely be a pole.

Here is the P_02 tower (cut) showing the R01 node and the radar would most likely have brackets attached where the red arrows are at the top of the pic.

So that is usually why the node name changes, because the object has to change location. Even though the location looks very close it is actually different.

That makes sense, but the thing of it is i did actually purchase the radar again but it would not turn on.

i am playing a modded game, but all the UPC and sub performance files are completely stock from SH 1.5. I went out of my way to make sure i didn't change anything that involved weapons,Ammo or Upgrades.

Maybe i had a corrupt save, but its really strange that by changing it from R01 to R04 it works and the Antenna seems to be in the correct place.

I had the same problem.
Propoise boat full conning tower air and surface radar.
Received half-cut tower, lost both radars.
Bought air and surface radar, only have air radar in sim and surface radar acts as if it is not there with no radar items on tower in 3d view. sub equipment display shows surface radar and it get's damaged as well.
Bought surface radar again after patrol, still no show on boat.

I too cannot get my radar to switch on...have edited the files you mentioned Warlord but nothing.

It shows as installed when I am in dock...but when I go to sea and look in Subsystems I am not seeing it there, all i have is SJ Radar Cabinet.

Cant switch on.

Having a look externally at the sub (Sargo) there is a pole with two metal prongs coming off it (I assume this is the radar ??)

Any thoughts ?

It has to be something to do with my saved games.....as I started a new career in Oct 42 and radar works.

Loaded one of my save games and it doesnt :wah:

I'm still not sure about this issue. The fix i posted worked for that campaign, but on another campaign i had issues again.

You would think that after 5 patches issues like the conning tower upgrade and the deck gun bug (Moving it fore or aft and losing the crew positions) would have been fixed, but it must be something weird in the files that is hardcoded or else i'm sure the modders would have fixed it by now.
