Moving textures from a wadfile in a .pk3 to a directory worked well enough, but there was a side effect. When I was using the wadfile, it superseded the iwad and showed the textures I wanted. Now, the iwad takes precendence and all of the textures that were replaced now show up instead. So now I have to find all of the textures I replaced and change their names. Then I have to go through all of the maps and change all of those textures.
