This is a old test that I did some time ago in blender 2.37a, the goal wasn´t to fake SSS, but the results seems to be something like SSS but never working on it again.
Now after seeing in other forums some test about other fake SSS I decided to show what I`ve do, maybe you’ll find interesting
and what do you think? is like SSS or not? the time to render each frame was about 8 seconds with internal renderer (blender of course).
