I am trying to anderstand and implement in Mantra some real skin SSS,
i came to the end result by experimenting that pathtracing SSS is the way to go.
But i'm just a newbie user of houdini and i have no background in maths or science,
given this paper for Renderman : RenderMan's Path traced SSS paper [graphics.pixar.com]
Can someone show how to implement this approach inside Mantra's custom shading ?
Attached image is my test so far (forget about the displace disgusting thing i'm sorry).
I hope this will challenge someone to make it ! as skin sss is like a graal for a lot of folks
including me

Thanks for your feedback,
++
