Hum well, I'm always honoured to find out that someone does better than me on the topic of ISL, you never know :D

fused also did an intro to ISL iirc. Sorry I must take off now !

Another crack at the infinite head.
This time the scattering coefficient has been increased to 5000 m^-1 (mean scattering distance of 0.2mm)
There is also a skull model underneath the skin (thanks FakeShamus!). The skull is green (for testing) which explains the green patch under the eyebrow.

I also made some optimisations for heavy scattering SSS that increased the render speed by more than 2x!

That looks really neat! I suggest that is rendered on your Laptop?!
Can I ask if there is a future for Indigos Dermis/Epidermis skin system, or does it get dropped in favor of "simple SSS"?

Nah it's rendered on his beastly new Ivy Bridge box :)

Another head render.
Fixed the skull colour (now dark red).

I also added dithering to Indigo, so there are no longer nasty banding artifacts visible on the dark grey background.

Todo:
* Vellus hair for asperity scattering
* oiliness map

looking good...
on my tests I tried reusing the albedo and bump maps as exponent and fresnel maps (I don't remember exactly which was better) it's a hack but it did basically work for varying the sheen of the skin.

ps- dithering is actually awesome!

Sure, they're still there and you can still use them :)

Spot on Nick, great renderings of the infinite head ! It was about time to use a blocking shape within !

I suppose that Zom-B is assuming that the dermis/epidermis system is old, thus far from optimized - so would I - and by extension I would ask wether it is also concerned by the new awesome SSS optimization. Or, should that dual system be considered as optimal or nearly ?

TBH with such results as currently I'm not bothered much about it !

Hi CTZn,
SSS optimisations will affect all SSS with high scattering coefficients, so dermis and epidermis media are included.

How well would Dermis stuff work with the the new coating material?!
