For those of you with an interest in the details and the math, I have not made a perfect match, but I'm closer than I used to be on how to match the Reflect node's softness (blur) with the Blinn node.

Here is what I'm using for a better Blinn (BBlinn)

def BBlinn(blur, maxValue=40, color=WHITE):  

     return Blinn(color, .03 + .065 * blur, 1, maxValue * (.5 ** blur))

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
