I been looking around as I want to use the different textures of the werewolf model for the Mo' Creatures mod. I know how to make it to the werewolf model but I been wondering how to make the texture different as the model has four different textures. I have just been so confused and hope I'll understand what I'm doing wrong with some help here.

You can't provide exactly the path to a texture, however, if there are different types of werewolves (i.e. they have different textures) in the mod, then try killing different colored werewolves and take a look at the morph's NBT data. Different colored werewolves probably have a different NBT value for every type.
