See, this shader is a prime example of why I can't get my bloody head around nodes in Poser!

At the far end there's a Reflect node, but ultimately it ends up feeding a Diffuse channel, and I just cannot get my head around that for some reason.  It's not like I'm stupid either (well not overly so).  I just can't grasp what's happening along that chain because what is feeding it is a reflection node.

I used to balance relfection with diffusion in Bryce, so I think I get the connection there, but I don't get what it is that is being supplied by the reflect node.  Like if you could see what is inside those wires between the nodes, what on earth is the reflect node sending that is of any use to the other nodes, that's what I don't get.

I wish you'd hurry-up with that missing manual, aRtBee, cause this stuff is driving me nuts.  Maybe it's because I'm too set in my ways from other software, I just can't grasp it!
