I have color A and color B and you want sub surface scattering. My question is, on the "thickness" map, does pure white represent complete translucency or does grey?
White would mean I'm taking 100% of color B right? Which means color A will not be present at all which isn't translucent. So my guess is .50 (grey) is the true value if you want both colors? Or am I wrong?
I already tried this with principle shader with red and blue creating purple with .5 (grey) sub surface scattering:
If I have white, I would be taking 100% of color B, thus there is no translucency with the red.
So my basic question is, when I make a sub surface scattering map, should I be using grey for max translucency? Or is there something I'm missing here? Because I have seen White areas in thickness maps before which makes no sense to me, you're just taking 100% of color B?
