Unless your horse is hairless, you wont need SSS.
You also don’t need it for the most part with humans.
Yes, but it’s soooo Mdm Toussauds…that lovely, waxy look is all the rage.
ROFL, don’t forget the cheap orange suntan, or the boiled lobster look.
Ahhh….yes, the spray on bottle tan…
I’ve thought about changing the colors to some nice greens and blues for doing some Bruce Banner/Hulk renders…you know that nice ‘radioactive’ glow look…btw Co-60 (radioactive Cobolt) does glow a wonderful shade of blue…
Now a little more serious and a bit more on topic…a very subtle SSS shader could come in handy for a horse, because hair is a ‘scatter’ material, it would need to be very subtly done. But it would probably be better attached to any hair as opposed to the skin (of course if displacement is being used to get a ‘fuzzy’ look, it would have to be the skin).
