@ Kpt, Otto: My timing is terrible. I was hoping to get it to you before you actually asked, but anyway here is Sean's Complete TexPack, with all the skins he released. This was one of the very first skins made for SHIII.

@ Mikhayl: I tried everything I could think of, but no matter what I imported where, I had no luck. I hope you can fix it, because even though I don't use it for my own boat, I like looking at it as it goes by in the harbor. The correct one is "Type IIB Line Camo".
@ nikbear: Go into Data/Cfg/Basic. You'll have to look down the list aways, but if you dig deep enough you'll come to '[SUBMARINE_AMMO0]; IIA'. You'll see one of the values as 'ForeResIntern=2'. Change it to 3 and you should be good to go. And if I'm wrong I hope somebody smacks be before I can do any real damage.
