Yeah, but it is the case yhat I tried all my abilities to
get BMRT2.6 accept an HDRI on Linux...and it worked so bad..

this is very nice...

I agree..

I started to work because a good looking skin shader is what MakeHuman needs...
..and I am happy to do this for MH.
But, really..I started this project without knowing if
I could get to goal.....
So, I am coding also to learn more..on yafray.

I don't want that you leave the shader because I am working
on it....

I got a first result now...but it has to be improved a lot.
I took as first model skin.sl from Matt Pharr (Exluna).

It is a simple one....my ambitious final target is to implement
a more sophistcated and general "translucent" shader...like in Jensen paper..
.."A Practical Model for Subsurface Light Transport"...but at the moment
it seems so far...

What the guys from MH needs is a working shader, not a "mine" shader..

Well, I don't know, let's see what comes out from the actual skinshader...
...and discuss on it...
