Large Modern Tanker not being detected with sonar
 

I’ve had to take a couple years off from SH4. I’m back picking up where I left off. One thing I noticed this time around, which I don’t remember being an issue before, is that the Large Modern Tanker is not being detected with sonar any more. I started out in the S boat and I am now in a Gato. But the Large Modern Tanker can be 500 yards steaming at flank speed and there is no sound on sonar, no detection on the displays either. The crew can’t detect it either. Is there something I can change in a config file to fix this? All of the other ships have no problem being picked up on sonar.

What happens if you take out the bottom three mods in your list (especially the last)? Also, do you have Large Address Aware (LAA) enabled on the SH4.exe file, if you have a 64-bit Windows OS?

Unfortunately, this is a Stock game issue with many of the Stock game ship units that most mods do not address...…..even the well known mods like TMO, RFB, GFO, or RSRDC.

The ship unit is in easy sight of the players sub, the Sonar man will even find the target unit and report it to you by way of the Text Message box, yet when you go to the Sonar/Hydrophone station you'll not hear the ship at all when directing your Hydrophone towards the target. You can get an active sonar "ping" off of the target, but the passive sonar Hydrophone sounds of the engines are not heard!

Now mind you, this won't happen all of the time, nor is it confined to just one ship unit. It's completely dependent on what speed the ship unit is travelling in the mission between particular waypoints that produces this "deafness" of the passive sonar capabilities.

It took me a while to figure out why, and do a complete "think out of the box" reconfiguration of each ship units characteristics but the latest v8.0 Fotrs Ultimate (soon to be released) will fix this problem!

I have no plans to make a compatible fix for the other "mega mods", but Fotrs Ultimate v8.0 will correct this issue. It's not called "Ultimate" for nothing!! :up:

Yep that describes it perfectly. Thanks for the info. I had removed the last three mods as suggested and was in my second patrol, hoping for the Large Modern Tanker to show up so I see if that did anything. You saved me some time.

I had been planning to do a complete fresh install per Rockin Robbins SH4CMS followed by installing FOTRSU, for some time but I was waiting to retire. Now that I have retired, and no longer working 55 – 60 hrs per week, I thought I start my return to SH4 by playing a career first with my current configuration. I think I’ll finish my current career first and not worry about the sonar issues. And thanks again.

And in large part due to the great CapnScurvy, Fall of the Rising Sun Ultimate v0.80 is out--the only mod so far that fixes this problem. Of course, we're out to make Silent Hunter 4 better and won't restrict others from using our fix, which represents more than six months of work by CapnScurvy, propbeanie and s7rikeback, the three horsemen of the apocalypse!

Japanese submarines show up on the map with the sonar bearing line but sonar never reports hearing them, even I cant hear them at the sonar station. Sometimes even at zero knots they show up as moving 12 knots throwing the fish angle off The recent FOTRSU ... great mod though. I love it.

took me a while to find this thread!:03:

i am running the current FOTRSU 1.8 (Not the previous one) and i am experiencing the detected surface contact that refuses to be detected manually at the hydrophone station. the contact is a PT boat, doing approx 16 kts.
the soundman announces his presence periodically, and we can see the blue sonar line on the nav screen, but nothing appears on the hydrophone, which is unfortunate because we cannot get a range on the little guy.

driving a Sargo out of Brisbane. August 1942. Started in Manila. Mission #5 or 6.
playing FOTRSU 1.8 with S7rikeback's Maru mods and Jimimadrid's sailors and torpedos.
i'll attach the JSGME mod list later, as i am in the middle of a mission and using a different system to post.:salute:


p.s. the lack of detection must be related to the PT Boat because we are now detecting a DD/DE Kisaragi and she displays on the hydrophone.

If you are talking about the JP Gyoraitei from keltos02, there are some issues with it, similar to the Sen Toku sub in Stock and all mods. It is perplexing. Combpounding the issue though, if you zoom over to the boat itself, it is "silent" - no engine sound. We have resorted to a big hammer... they seem to be cooperating for the next release.

no, it's the NPT_JP.
and, no, i did not use the external camera to eyeball the little darlin' so i did not hear it not make any noise.
i just wanted it to go away.:03:

i was hunting and didn't want the little bugger in the vicinity to muck up my game.

i would have taken a shot at him but you cannot see those little buggers unless they are close enough for them to shoot at you, and that is not going to happen.:salute:
