Seen a couple posts related to this, so I figured why not.
Hope at least 'someone' can make any use from this =p
If theres another guide explaining this just tell me (I couldn't find any).
This'll show you how to find what textures & their tree-paths (in wow mpq files) are used on what models. Can be useful as not all texture files to models are obviously named and listed in the mpq's.
Tools:
My WarCraft Studio
Model Viewer
Cryect's Tools (M2Modder)
I hope for at least 'one' person to make use from this somehow
