NHF – new heroes for Heroes V 3.1.

It seems like the mammoth has a different mask (sometimes it's not there, sometimes it's spiral-shaped, and sometimes it's angular).

Well, that's not a problem – we can create that specific prop and attach it to the standard mammoth, but as I remember, it's just a different texture, meaning the geometry is the same, but they used texture transparency to make it look different!
