Inspired by the upcoming game LEGO Star Wars: The Skywalker Saga, this Texmod pack is intended to bring the character designs of Lego Star Wars: The Complete Saga a bit closer to what LEGO is currently producing. Though most of the textures are at the original resolution, the pack should give the game a slightly more detailed and movie accurate look. Requires the use of Texmod or uMod/OpenTexmod.
If Texmod isn't working for you, give this a try. It's slightly more complicated, but apparently sometimes works when Texmod doesn't. The instructions are for Assassin's Creed II, but you're going to want to use LEGO Star Wars: The Complete Saga instead.
