TexMod
From Tomb Raider Wiki
TexMod is a program for modifying the textures of many games including Tomb Raider: Legend, Tomb Raider: The Angel Of Darkness Tomb Raider: Anniversary, and Tomb Raider: Underworld. By using this program, people can extract textures from the game, recolor them using a photo-editing program, and then build a package so that other players may play with the new outfit or level color schemes.
Other than the Tomb Raiders, TexMod is compatible with a lot of other games.
Along with Tomb Ripper, another texture modifying program, TexMod has been instrumental to creating a Modding community for the new Tomb Raider games.
