That is some informative information. Even so, I'm running into an issue. I adjusted some of the values in the sim.cfg, and got the Bismarck to detect and fire at me at about the same range as my own crew would fire back (about 14000 yards).

I can't say the same for the Japanese vessels. From the Yamato to the Fuso, they don't detect and fire until about 9500 yards. What is different between the Bismarck vs. the Japanese ships to have such a disparity in range? Does it have something to do with the individual ships files?

I'm testing a simple mission, Fuso vs. North Carolina, and Fuso maneuvers and engages my ship at 5 NM. I haven't gotten it to increase from there. I can't really tell if the ship isn't detecting me, or is waiting to get into firing range. 14" guns are set well above that range in the sim file, and here is that area of the sim.cfg:

[AI Cannons]
Max error angle=5 ;[deg]
Max fire range=20000 ;[m]
Max fire wait=8 ;[s]

[AI detection]
Lost contact time=30 ;[min]

[Visual]
Detection time=0.5 ;[s] min detection time.
Sensitivity=0.01 ;(0..1) min detection threshold double detection time.
Fog factor=0.5 ;[>=0]
Light factor=0.5 ;[>=0]
Waves factor=0.5 ;[>=0]
Enemy surface factor=1 ;[m2]
Enemy speed factor=1 ;[kt]
Thermal Layer Signal Attenuation=0.5

Anything that I have set wrong that would cause this? Is there something buried in the actual files for the individual ships that determine any of this?

Check this ships SNS file. Look at what visual sensor they are using. Sounds like they might be different. In TMO i added extra visual sensors. Some are freaking huge in radius, other's small. I applied these various visual sensors to what seemed logical. (IE big radius on battle ships, small on merchants).

RFB does the same thing i believe, as does RSRD. So if you have any mods installed (or previously installed), you might want to check your files to make sure.

Open the AI_Visual in the Library folder. Find AI_Visual and open the obj_sensor and change the settings there. I believe there also is a AI_Visual_Sensors. Do the same there, I don´t know if this file comes with mods or just a part of stock.

Just a little update to this question. Thank you everyone for your help. I found that the IJN BBs use AI_Visual as a sensor, while the Bismarck used BB_Visual. I think I will just switch any ships I use in my custom missions to their respective type, like BB_Visual, CA_Visual, etc. I now can get the firing performance I was looking for out of the surface ships.

I'm still having the same problem FighterSteel1 encountered,
even though I highly increased the gun range in all the files up to 35,000 meter, but the gun range actually seems to have worsened - it is only 5000 yards now and below... What am I doing wrong?

I edited the following files for visual sensors and radars:


AI_sensors.dat in \Silent Hunter 4\Data\Library

Sim.cfg in \Silent Hunter 4\Data\Cfg (for example I increased the Max fire range to =35000)

guns_radars.sim in \Silent Hunter 4\Data\Library\ShipParts

What did I forget?

Oh, and of course I changed the Iowa's gun range too, in the mod folder, the file containing is named "Deck_Gun_16Inch.sim" (is that the correct file to edit?) It has the ID 0xc067bf9f3ab70a36 (can anyone confirm this?)
and is located in \Silent Hunter 4\MODS\USA_Iowa\Data\Librar\USSubParts. The original gun range was 38720,0 then I increased it to 157720,0.

But it still didn't work... What am I missing?
