Interesting. This person has been reading my postings on how to manage AO strength in a material. There is also a Bias node, something else I posted about. It allows for more direct control of the AO shadow evolution. It is, however, acting as a pass-through at the moment, with the Bias being .5.

Can you show me what is in the Image_Map_4 that goes to transparency - just open image map node previews so i can see the patterns in them. Otherwise that's a total mystery to me as to what is in there. I need to see the image. If it is all white it doesn't matter.

Also, I'd like to see the EyeSurface material, please.

I might ask for cornea and iris later. If it's handy to show those while you're at it, do it.

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)
