Quote - That's correct.  Ready for a little lesson?

The reason we don't want it involved in your shader is because I'm handling the diffuse stuff somewhere else, taking into account gamma correction. Using the built-in diffuse node, I can't intercept the output and gamma correct it. So I turn the whole thing off.

Wow, thanks for the information.  This is what I have found so fascinating and ingenious about this shader.  The only nodes that are working are the alternate diffuse and bump.   A massive amount of intricate calculations go into one single place to define the light reflections.  It makes lots of logical sense to me, but I'm a math teacher, so I have a hunger for simplicity and logic.  The PR3 is so nicely organized I had no problem doing little tweaks to alter it slightly.

However it did alter the shaders of all figures in the scenes to their "body" and "preview" domains.  (And the "tongue" of a boot I had in there, LOL).  Somehow it turned the pants white, even in the render.  I haven't figured that part out yet.

I learned a ton about Poser shading from this, so thank you again.  Being a Carrara user until I've recently decided to learn Poser, I had to dig deep into the concept of shaders (since content rarely includes anything Carrara can use), it's wild to use something this complex, and a great experience to see how intricately it can be used.

Thanks.
