ok - decided to try out the msss_fast_skin_shader. i'm using the mix20layer shader from pixero.com with the msss_fast_skin shader and a blinn for specularity. everything still needs a bit of work so ignore some of his craters.

i've been following a tutorial from gnomonology on skin shading. however i'm having some difficulties attaching the displacement map. I figured it would be plugged into the mix20layer's shading group, but nothing seems to happen. i also tried adding it to a separate blinn that i add as an overlay, but still no luck.

any ideas?
