How to import custom model into WoW.

[DrSandwich]

Hey!
I want to import custom model into WoW, so it would replace a character.
Is there any way to do that? I tryed MPQeditor, but MPQs are locked, and do not allow me to change models and stuff.

If not, then is there a way to convert .m2 files into OBJ?
(By that i mean a model that's in .m2 format and not's in the game).
Thanks.

Don't try to edit the actual mpq files. Just create a new one with the models you want.

I created an .mpq file just as you said.
I put the model, textures and all other stuff in it.

Now - how where do i put this .mpq file?
And also - it is able to make this file readable by WowModelViewer?
If no - then is there ANY way i can convert this model into .OBJ format?
Thanks.
