Just looking at the candle shader. Good job I have a bit of programming background, or this whole thing would be Chinese to me. Question:

        # y = Distance from top of candle - anything above Vtop will be
        # considered to be at the top for diffusion purposes, thus the
        # Max with 0.
        y = Max(0, Vtop - V)

Where is V defined? Is that an internal Poser constant?

I forgot to answer this. That is the V_coordinate node. It is not a constant. It is the V coordinate of the point currently being shaded by the shader.

In matmatic, I use these a lot. I mean a lot. Really a lot. I did not want to type U_coordinate and V_coordinate over and over. So in matmatic they are simply U and V.

Think of them as global variables, read only, not constants.
