i think the blinn node needs to be fixed. all the nodes made when Poser didnt have gamma correction. IMO the blinn node doesnt work perfect with GC.

i think we need a better specular node. and i think we need a cloth node. something for clothing. something that has sheen .
i want to render out a simple sweater or t-shirt. but with the poser nodes it doesnt look good compared to the skin.
