Subsurface on grass with pivot painter

Hi all,

I’m dounsg some test with pivot painter to have a better control and trying to achieve a more realistic grass. The actual shader is based in some tips from “Rens” foliage shaders. I have exagerated the SSS in order to see easily how is working but the thing is, that after generate the pivot for every single blade of grass with pivot painter 2, the backside of the foliage isn’t working as I desired. Some of the oposite faces of the blades of grass looks like if they where facing the sun instead of getting light passing through them. I don’t know if I’m explain myself properly…

This is how it should looks:


And this is how it already looks:

As you can see not all blades are getting light trhough them…

Any ideas? It shoul be related to the pivot of every single blade? In taht case any ideas of how to fix it? Or any tips about Pivot painter because the documentation is quite sparse…
