Hey, okay Bob, lets get you going
I am named Bob too, hope you dont mind me calling you such.
First, go to this place, and take the trial version of Paint shop pro 9
(need to create an account first)
http://www.corel.com/servlet/Satelli...=1047024437292
Thios program can open and alter TGA files, the Files you are looking for.
TGA files are like Bitmaps, or Images, and contain the "skins"; or "Paintjobs", as i prefer to call them.
lets say you open one of the uboat skins, NSSUboat7.tga or something
Open one of them and, in the top bar, choose "Layers" and create a new raster Layer.
Now you are putting one new empty image above, but not on the tga file you opened.
you can now work on your new layer, paint on it, modify it as you wish put a shatkmouth on it, or a smiley. Or paste a whole new Picture on it-your mind is the limit.
when done, save your project as a paint shop pro file, and you can restart later on, where you quit.
to see your work in the game, save as NSSUboat7c.tga file, and put it in the
SH3/data/textures/TNormal/tex folder
Done
Okay i suppose you are shurely stuck at some point here and might be coonfused a LOT whzen you first open up a TGA image.
shoot away your questions, i have patience to spare
and will check back on you tomorrow.
