Changing ground textures?

Hey guys, I really hope you can help with this.
I want to change the textures of some of the ground in WoW, like done in this video:

I've downloaded Mywarcraftstudio and WinMPQ for the archives, but can't find any of the ground textures for elwynn, stranglethorn etc.

And at last. Can I save it in Patch.mpq (if it's that mpq the files lie in) or shall I make a new archive with the changes? (I'm gonna play on a private-server, so hopefully it won't say that patch.mpq is damaged or something like it)

Hope you understand it, and that you'll help :rolleyes:

can someone please move this threat to the modelchange forum

all groundtextures (aka tilesets) are in the commom.mpq under the path "Tileset\", for example "Tileset\Elwynn\" ;)

you shouldn't edit the orginal mpq files, you've to create a new one called "patch-4.mpq". then you must put this new mpq into the "world of warcraft\data\" folder :)

Geht nicht^^

was fake!? =D

Thanks Parl, you're the man!
Got it working (changed some of Elwynn's floor), so I'll work on it, and see if I can do something fun, if it's turning out well, perhaps I'll upload it :)

Sorry for posting in the wrong forum :/

<hr>Append on Jul 9 2007, 09:33<hr> Hmm, I've got a problem now. :rolleyes:
I've changed Elwynns ground texture and a bush, but some of them (like the small detail ones seems unable to change :/) I've done the same to them as the others, put them in the right folder etc. but it still won't work.
If anyone knows how to fix this, please help :P
