Fred, I thought so too but pretty long time ago I wanted to modify one industrial texture (factory.tga). So I modified it, went to game and saw no change relative to original. Then I thought maybe since i modified only the tga and the tgb is unchanged and it's bigger size, maybe then the tgb represents the long sighting distance texture, so maybe I see the difference if I increase the sighting distance. but nothing changed...However when I changed afterwards the corresponding tgb then the result was immediately visible in game.
