(playing a bit more with it)

 

I have a funny effect. I'm using EZskin on the "William" texture set (http://www.renderosity.com/mod/bcs/william-for-m4/68080), and depending on the starting shader settings (packaged pz2 which installs plain maps for diffuse and bump) and a manually implemented SSS version with one of the shaders posted at RDNA, I get different results despite same EZskin settings.

The most obvious difference to me is the treatment of the bump map (my setting was "prefer bump map" in both cases.

When I start from the plain pz2 file which comes with the package, the bump map is plugged into "gradient bump" and the procedural bump into "bump".

When I start with the SSS shader, the bump map is plugged into the blender node which goes into the regular "bump" channel.
