If you use taliis (not recommended) but IF you do. then what you have to do is go into Noggit and alter your ADT's individually ( Hit F7 and every Green outlined block is an ADT) Alter somehow maybe with the Raise tool or something. Once done. Hit CTRL + S or Save all in FILE. then hit SHIFT + J or Reload ADT and itll fix that ADT. I don't recommend it because at the moment I am actually having this wierd barcode going through my textures when I do it that way. But still trying to figure that one out.
