Warning Will Robinson - Warning! Potentially horrific file conversion ahead!"
OK, in the Torpedoes.dat
(torpedo selected as an example). Make certain that you have the correct texture, either by copying and searching on its ID, or double-checking it when looking at the names - check that the ID matches. We personally know someone who spent half of a day noodling in files, only to find later that they had edited an incorrect texture... sigh - Anyway, here:
match the IDs. knowing you, this step is probably correctly completed - but just in case. Then, when you open the file in your editor, it won't look this bad, but... (bad conversion for imgur - yikes):
you should still be able to get the idea... The more or less rectangle to the left is the body, those circles at the bottom of the added blue rectangle go inside those half-circles on the tube "wrap", and just above the "circles" is the "cone" with a "circle" at its top to fit the pistol through. As you can see, you now know why I leave textures and other files of that sort to other, more competent people... sigh.
