Indigo Renderer Forum

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

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

Wow. I am so amazed by your work kklors... Impressive is an understatement.

Ono, please feature this on the front page asap!

I'm trying to get a hold of him for an artist interview

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"?

Speedups are like free beer, always welcome!

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!

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?!

Some ultrasonic air transducers...
