BB can do anything, absolutely anything (apart from Anamorphic stuff I mean).

But anyway, regards the Mud Shader, it wouldn't surprise me if Baggins is hard at work, noding feverishly on 'BB_MudWrestle' as we speak!
In fact, I'm guessing it will be a take on his awesome Chocolate Shader, and trust me, that one already has more potential than Chocolate Bunnies ;-)

@Teyon
Thanks for the renders, looks good :-)
