okay...thank you both very much for your detailed answers
@polyfiller:
so what I gather is that I need the sim, the dat and the upc files...that's very helpful thanks. Yeah I tried rotating them as well, but the torpedo comes out horisontally, but what the heck, that's only eye candy in a way, most important is that they work
oh by the way....the basic cfg is of no use really in SH4 contrary to SH3 where it was a key file...that's my experience. I think that most stuff in SH4 is decided by the UPC files only small details like key commands, and realism settings etc. the basic cfg has an influence on. It's rather confusing compared to SHIII hehe
@Keltos:
It's on German side....I've made the Foxtrot class German and I'm now trying to make a Golf class out of the Foxtrot.....I've alredy added missile hangar long time ago and thanks to your excellent german fliegende torpedo mod I also have missiles, only it would be perfect if these had their own tubes which could thereby limit the numer to realistic 6 pieces of them and if they could launch vertically from the missile hangar. I've also made the flying torpedo look more like a missile....it's primitive work because I have no graphics program so I have to clone all that I do with existing parts, but it looks decescent enough for my use

.
Well thanks both of you for helping....I'll get started doing those tubes.....
