Freelancer uses 2 types of TGA, INDEX & RGB, you realy want to be using a 24 bit uncompressed and vertically flipped RGB TGA. This means 8 bit RED, 8 bit GREEN & 8 bit BLUE colour channels, if you have a 32 bit tga then you also have an 8 bit Alpha channel which is useless on a ship (useless on most other models to).
Flipping a TGA confuses a lot of people as they think it's something wierd and difficult, in photoshop it's under the "image" dropdown menu, highlight the "rotate canvas" option and the tree will show 6 new options, the bottom one is the one you want "flip canvas vertically". All it does is turn the canvas over so the Top is at the bottom and vice versa.
If you have either Paintshop or Photoshop then head to the Nvidia site and get the DDS plug-in as DDS is far better IMHO than TGA (I've converted almost all of the vanilla TGA's into DDS).
Back faces aren't really an issue as FL just won't show them, most of the vanilla ships have back faces but because thier double skinned you don't realise it.
For a noob using HardCmp is the easiest way to hardpoint, once you get more experienced then you can do it in Milkshape.
The 3DB file is the icon you see in the shipdealer, that little picture next to the the name & price. just do what you were doing and us a vanilla one for now as it's not important yet, you'd be surprised just how many people don't make icons for thier ships.
Hardpoints don't you just lovve them
It's surprising just how many people don't know the right names and numbers for them. Take a look at the FLSpew file after you've run a big mod and all you see are dozens and dozens of "missing hardpoint" errors. Caused by misnaming them in the CMP or INI or by forgetting just how many were in the CMP to start with.
@ Leopard2A6, send me your textures and I'll send you them back as beautifull DXT1 DDs. If you don't want to try P2P and download a hacked copy of Photoshop, then I'd recommend the GIMP as it has most of the features of photoshop.
@ Rankor, Photoimpression4 probably saved them as compressed by default, where as Paintshop, the Gimp & Photoshop save as uncompressed.
