i like what you have done Bagginsbill and i would like to see the how you reduced the shader to 6 nodes.
I have no idea how you add fresnel or accurate fresnel, but im sure i will pick it up along the way...lol...

JWFokker:- i think for version 3 i will do a (from the ground up) new mud shader that looks like that image you posted...very nice...(now im gonna have to scour the internet for a larger pic so i know whats going on....

Oh and on the wood front... i dumped the wood nodes and made quite a nice looking effect, but still i enter the You can change the scale in the way you want or rotate how you would like, or apply to only one facing direction.....i hope they make the shader room a little more friendly in the next poser incarnation...lol

Getting old and still making "art" without soiling myself, now that's success.
