So, you want to know what the hard way is?
Is a more dificult way to install the mod.
There's a .big file, that you have to merge with your current texture.big,
and a .bin file; you must go to game.bin > 10535 - (CHeroMorphDef), 
click on import and choose the file with the same name as the entry.

Why I added the hard way to install?
Because, sometimes, the textures in .fmp (Fable Mod Package) are corrupted and they
ruin the in-game texture, making it dizzy (instead of th e texture you see
rainbow colored and black dots over the body). That's why there's a "Hard Way".
