I am copy and pasting this from my other post so other people can see it too and we dont have people asking the same question
Please Note this is a rough version of what is to come and is simply a synapsis for those who pick it up from this great.. for all others.. ill do the work later=)
Ill take the time to write a more detailed guide up if you really need it, but for now.. Find the instance you which to change TO in both the patch.mpq and the terrain.mpq and extract them both. overlay all of the patch.mpq files into the terrain.mpq folders to make sure you dont miss anything. Now take the file you know it fits with (The most common is Scholo-ED) and use a batch renamer to do all the work. I.e Change all of the .adt's .wpl, and .wdt from say EmeraldDream_25_29.adt to SchoolofNecromancy_25_29.adt. Be sure not to change the tile panes (the #'s) Just the names.
1) Go into MWCS and create your speech2.mpq.
2) Add the folder with the correct treepath, For Scholo it should be world\maps\schoolofnecromancy\schoolofnecromancy_*_*.adt, wpl, wdt ect.
3) once all of the files are correctly implemented save and close under (p)
4) Drop the speech2.mpq into your data folder and zone into scholo.
Note: Make sure you have at least 76% health when you zone or you will die, as you typically fall quite a ways.
Extended notes: You cannot do all instances to all instances, sometimes the files just dont fit. So alot of it will be trial and error.
Hope this helps, Best of luck
