Thank you Bill... just confirming your previous offer.

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?
