Proble with 2Sided material and render elements

Hello everyone,
i have a problem with the 2Sided material.
How can i extract the translucent effect with renderelements.
I want render a few passes (lighting, gi, reflect ect.) that i want use in compositing.
It seems that the 2Sided-effect don`t show up in the lighting pass.
I it possible to extract only the translucent-effect like the sss-effect ?

Thanks in Advance

Currently it is not possible to extract translucent component of VRay2SidedMtl in a separate render element.
