Its a newbish question but I couldnt find an answer anywhere. So if I have custom textures, will they be applied to TR content? I mean does TR use same base assets as Mw? Hope Im being clear

TR has a thread http://www.gamesas.com/topic/1414087-relz-tamriel-rebuilt-sacred-east-12-4/ for questions like this.

The answer you're looking for is yes, and no. TR adds many new textures, but for the most part it uses vanilla resources in order to blend in with the rest of the game.
