Head model is the 'infinite head'.
Scattering coefficient is 1000, but it's still too low :)
Looks greasy :P

Would it be possible to have a play with that scene? Maybe a different light setup could show off the SSS a bit better?

I have attached the head scene.
Render with single-directional path tracing.
Displacement could do with a bit of tweaking as mentioned by Zom-b.
You will have to download the head model + textures yourself and adjust the paths in the IGS file.

Trying out different displacement parameters:
b = 0.006, c = -0.003 (so that mid-grey is zero displacement)
texture exponent (gamma)=1.

it looks right.

mudbox and ZBrush use 50% grey as zero displacement, probably the authors of the head data went along with the standards.

thought I'd give this head a try - took a lot of tweaking to get the absorption working half way decent, it doesn't use any scattering. basically blended glossy transparent and phong. still a bit waxy I think... I'm attaching the .igm (sans textures) if anybody wants to play with it.

gave him a "skull" and added some sss to the skin material, now he's not so dead.

Good stuff!
How did you do the skull?

Copied the head and scaled it down, trying to give it even space all around. then cut of the ears and nose and dug out some eye sockets. Made it a dark red diffuse. The SSS takes a long time to converge with this material, any tips to speed it up?

I've read about a simple trick to "fake" the front end textures of the board:
Use the same texture as for the side of the board, but flip and scale a lot...
Maybe you can use it here?

Is there a "getrennt" versio of the chair? :wink:

Hey cotty, good point about the texture, will do as suggested :)
The image of the chairs is a based on 2 renderings, so you could imagine how "getrennt" would look like ^^

the petersilie is awsome :D
already 2sided mats?

somehow the fabric on your chair still looks.... hypnotic...
maybe you could improve the texture to reduce/avoid the tiling
