-Download Glitchy MES (the latest version)
-Open up 3DS Max
-Export your model as .OBJ
-Use Glitchy MES .OBJ > M2 converter
-Follow the steps
-Import it in a MPQ, and you are done.
I assume that you can handle UVW mapping and positioning on your own.
As a sidenote, you need the 3 following things to put in the mpq:
You need to render your UVW map first, make a texture out of it, and convert it into a BLP. If you just follow glitchy mes instructions, you will get a M2 and .SKIN file too.
