I am having problems with the BB shader itself. The eyecovers render opaque black, as this also happens for me when I render the original eyecover prop, it does not seem that my injection is the cause of the problem. Perhaps this is a version thing, I am using P6, but BB's have a version number of P8, or perhaps there is some extra instruction I am supposed to be following that I have forgotten about.

You're far more an poser expert than I, and if this is stupid excuse me, but do you have ray tracing on and enough bounces to cover?

(edited to add) and some thing to reflect?
