Is it possible to replace one .adt file with another to change the terrain? I attempted this and it crashed when entering the changed area.
I used MWCS to locate an area just south of thunder bluff (Kalimdor_32_35.adt) by estimating the location and then looking at each landscape directly. Then, I picked an essentially random .adt to replace it with (Kalimdor_32_10.adt).
replaced:
World\Maps\Kalimdor\Kalimdor_32_35.adt
with:
World\Maps\Kalimdor\Kalimdor_32_10.adt
(these are both found in the terrain.mpq archive)
Then, using MPQMaster 1.2.0, I made a new mpq, patch-8.mpq, and inserted Kalimdor_32_10.adt
I then renamed it to World\Maps\Kalimdor\Kalimdor_32_35.adt
Now, when I load the game, there are no problems, however when I approach the area south of thunder bluff (even in thunder bluff) there is a
The data could not be "read" error (with blizzard's huge error report).
Is this a protection blizzard has placed on the files or did I mess up somewhere? Also, is there a way to modify *.adt files directly? (shifting vertexes and so forth)
Hope you can help
