SSS2 Compound

[rray]

Hey those are nice renders

I updated 1st post with a new version of SkinSSS2 and added the SimpleSSS2 compound

Kzin, diffuse having control over SSS was actually done by mistake. Although it obviously works out really fine, I repaired that in the new version because it's somewhat unexpected and some tuning control is lost. It's possible however to get the exact previous behavior by connecting the diffuse texture to both "Diffuse" and "Diffuse+SSS Multiplier" together - this is at least how it was wired by accident in the first version.

Old version still available here

Some other changes in the new version:
* Rendertree connectors/layout fixed, exposed "scale" for texturing and added Sampling Radius Mulitplier
* Tidied PPGs a little
* SkinSSS2 Compound has default values from Kzin's post above

thx, will test the new one as soon as possible.

first fast test with the new compound.
you have more control now thru the sampling radius multiplier, have to do more tests with it.

Looks so good I'm considering shaving my eyelashes

Here's a test I did with photon (lit with caustics only)

I'm curious about your lighting setups - seems like Mental Ray renders very dark unless I put an exposure
node on the camera, regardless of soft, ibl, or whatever. Without exposure on camera, when using
a spot (with attenuation, which I know will diminish the power), I generally have to turn up the
intensity to 200-1000 - just curious if this is normal. My models are all relatively to scale (10cm/unit).

Great renders - the updated sss seems much more powerful. One other question - is diffuse+SSS like an
additional 'scale' value?

@ second question: Yes, it's a multiplier or tint for the SSS and diffuse components. It is named "overall multiplier" in the original SkinSSS, I though I'd rename it so it's more clear that it doesn't affect anything else.

its ok, i had values of 6000 or higher for physical lights, but i render without exposure shader the most time. physical values are completely different to light without falloff and intensitys of one like in old school setups. physical sky shader for example and sun intensity values of 100 for ibl are normal settings.
