better volumetric skin
Issue #117
resolved
With some more tests it seems the volumetric skin may benefit from less density to better match the iray translucency effect from strong backlights. Below the equations that are the same as #24 I just changed the density factors.
# if there's transmission then use volume absorption
if transmitted color <> black/white
use volume absorption
color = transmitted color
density = 100 / transmitted distance
# if there's sss then use volume scatter
if chromatic sss color <> black/white
use volume scatter
color = invert(sss color)
density = 50 / scattering distance
anisotropy = sss direction
# please note that sss amount can also be > 1 in some characters
# this is fine since color slots accept values > 1
if mono sss amount > 0
use volume scatter
color = sss amount
density = 50 / scattering distance
anisotropy = sss direction
Also an example with V8 for the ears and fingers with a strong backlight. First iray then the plugin before and after the fix. Scene included.

Well, this was easy enough.
