Reducing Unwanted SSS Glow

Masterstroke

Found a solution for reducing unwanted SSS glow on small body parts like fingers.
at first, I've tried to create a sceleton to avoid that, Now I've found a more elegant way to do it.
Can you please try to reproduce, to investigate all the pro and con of this methode?
The trick is, to just add a geoshell to your figure and set the mesh offset to -0.10.

So the first pic is without the inside shell, the second is with it.
EDIT:
Ears still glow nicley with the inside shell.

What transmitted distance and sss scales are you using? I generally find them alone enough

Thing is, I am pretty helpless, setting up propper shaders. These shder settings are taken from a IsourceTextures Character. I've tried to include the relevant information in here.

Are you basing it on an older product? those settings don't even have chromatic SSS (and are just... weird in general)

Honestly before fiddling with geometry shells I'd consider borrowing settings from a different character - If you have anything by bluejaunte or mousso they usually have pretty good settings, daz core figures as well - or if you're feeling adventurous and want to use spectral rendering: use the isadorekeegan settings from the iray photorealism thread.

 

Honestly your after didn't really look all that much more realistic to me, just off in a different (and less jello direction). For instance, if i stick a flashlight behid my hand the fingers will fully glow red, my palm, however, won't.

 

Using extra geometry to try to counterbalance unrealistic settings seems like pushing a boulder uphill

For comparison my real hand when backlit with a flashlight (and yeah shining flashlights at myself to figure out physical properties of skin is something I do. Fun fact you can see the veins near the surface but because of how the light bounces around bones completely disappear

And for comparison a 3d hand. - significantly better camera quality than my phone

Iam still using the uber shader. I don't use bluejaunte's shader, because skin use to look pretty dark. Right now I am stalling to try PBR shaders for the same reason. It all looks way to dark for me. So right now ISourceTextures' just work best for me. except those SSS values are always a problem. I was hopening the shell trick would solve this problem.
Thanks for your Photo exsamples. See, they don't glow uniformly red. They have that darker areas in the middle, where the bones are. That's what Iam trying to get.

only one of them is a photo sample, the other is a render

That first one made me feel like I was tripping staring at it full screen lol. It looks like it is continuosly shrinking.

+1 ...and its been years since my 'carrot juice' days.
