Ah, as a new poster to the forums I am reluctant to chime in again, but those targeting zones do not appear in stock silent hunter 3. I've had to reinstall several times recently and I can assure you that in my stock installation those zones are simply not present. I see that the torpedo path changes as you said earlier, and that doesn't happen in my stock installation either
I suspect your repair procedures or installation of what should be a res-only mod somehow changed something. Try removing ALL traces of silent hunter 3, making sure the directory is completely removed, and then reinstalling it with only the patch. Do not repair the installation, and don't install anything else. Those are the only differences between your reinstallation procedure and mine, yet we get different results..
(edit) I'm going to go ahead and follow my own procedure just to make sure I'm not crazy, too. Always a possibility.
(double edit) The zones aren't in my recognition manual. My procedure is as follows:
Uninstall SH3.
Delete the SH3 folder that remains on the hard drive. Reboot.
Install SH3. Install Patch.
Load Game, load Happy Times mission, confirm that no zones appear in the recog. manual.
I can't post a screenshot as that computer is not hooked up to the internet at the moment, sorry.
Hope this helps..
Based on Goose_green's reply, I'll try once more to get the zones to appear... and they didn't, even with an optimal setup in the same naval academy scenario Fong was using. Based on what other threads are showing, it seems I still need to fiddle with my config to get the boxes to appear, if I can get them at all. (fifth edit?) Ah, I can't get 'em to show up, even with a full crew in the torpedo room and an optimal setup. If someone else can get them to show up with stock SH3, I am all ears...
