I've got some serious problems with this, I'm trying to change Durotar ground to Tanaris ground... I'll try describing it the best i can. I open MWCS, use it to open common.mpq. Open "TILESET", open "TANARIS", pick "TanarisCrackedGround.blp" and click "Extract file to...", and extract it to my desktop. I then open "Durotar", pick "DurotarDirt.blp", right click and choose "Copy Treepath". Pick "Create MPQ Archive" from the "Pack" dropdown. Click "OK" when I get a window saying "Are you sure to close current archive?". Create the archive named "patch-3.MPQ" in my WoW/Data folder. Click "Add file to archive, choose the "TanarisCrackedGround.blp" from my desktop. Press OK. Right click it in the left menu and choose "Rename File". Press ctrl+V, now it's called "TILESET\Durotar\DurotarDirt.blp" and appears with a folder icon in the left menu (when I press OK). Click "Pack", choose "Save and close archive", close MWCS. Then I open WoW using my Modelchange.exe, go to Durotar and... there is absolutely no change. Do you have any idea what I did wrong?
