Once EZSkin P12 becomes available, that problem will become history. The blue diffuse chip color was a hack along with the activated red ambient channel to fake SSS. So I wouldn't rely upon any default shaders developed before P11.3/P12. Also, pay attention to node connections that are dashed rather than solid. The current iteration of Poser can detect bad or 'illegal' connections between nodes, causing Poser to render your models incorrectly or at all.
