What do you have your Poser Display Unit set to? I need to know that in order to interpret the ray bias in the reflect node.
Once we know your PDU, I will likely point out that your ray bias is .762 PDU - e.g. .762 inch or .762 meters. Then we will examine what that means. In any case, it's probably too high.
It is important to know what ray bias is for - it's to cause a reflection from a surface to ignore that same surface for a while. This doesn't sound logical and it's actually because of an undesirable artifact. It's a hack.
In your case, I am suspicious that you have curved the surface with your bump/displacement, and that the reflections of certain angles lead to the skin, but would logically not reach it and are only doing so because the ray bias causes the coif to ignore itself.
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)
