Not to be gross, but, whenever I get a deep flesh wound, the thin (well, for
me) fat layer under my skin becomes visible. Has anyone tried adding this
layer when using SSS to render skin? I would think it would make a big
difference.

"I think it would make a *big* difference" Is that a pun?

Hmm. The next time I let myself get so out of shape as to *have* a 
significant fat layer under my skin AND I happen to be so careless as to 
let myself get a deep puncture wound, I'll just *have* to try this...

Dude, I've read a lot of *interesting* posts in this forum over the 
years, but yours just went to Number #1.

  Normal-weighted people in good shape have about 5-10% of fat.

I think people realize all of what contributes to the complexities of 
skin color,... fat, bone, blood vessels, pigmentation patterns, but we 
have no method yet to directly simulate these as subsurface layers.  So 
to date, the alternative of using uv'd pigment maps is still getting 
better results.  SSS has been used to suggest the dramatic translucency 
that is apparent under specific lighting situations.  Variations in 
finish also contributes to the look of flesh.

Thanks Jim.

Hrrm, it looks like I was mistaken, it's probably not the layer that
contains fat, it's above that, probably the dermis since they didn't bleed
(above the larger veins) and it was white (under the pigment layer).
For rendering purposes, I suppose all layers under the pigment layer would
be white.

For reference, here is a nice graphic showing the layers here:
