To create a mod its neccesary...

[nck1990]

When you create a mod in warcraft III, the custom textures, models,etc. Its neccesary extract the mpq files, replace the archives and recompile the mpq files in 1 file?. Because a try to reeplace the files for my mod and the game dont recognize the textures, models, etc...

If you've imported them correctly to the correct paths, you just have to restart the editor.

Generally this method is not used though.

You can also enable local files and place them in their appropriate folders in the install directory. This way is technically more user friendly as it doses not permanently modify a WC3 install (you can delete the assets at any time).
