How do you edit texture in Jedi Academy?

Answer 1

In your Jedi Academy Base folder, you'll see several files with .pk3 extension (assets0.pk, assets1.pk3 and others). You'll need to use Pakscape to open up these files.

Open assets1.pk3, and there should be a folder called "textures". Copy it whenever you want in your computer, and there you go - you have all in-game textures in one folder. They are ready to edit - you can use GIMP or any other graphics program to edit it. Remember to save it in standard JPEG encoding - if you'll save it in Progressive encoding, the error will show up when you try to start up the game.

When you've edited textures, open Pakscape and copy the "textures" folder into it. Then, save it as "textures.pk3" in your Base folder. Done :)
