Subsurface not working in shadows....
I have been putting together a grass material, and my results so far are what I'm looking for. The problem is when a shadow is cast onto the grass it appears that there is no subsurface effects. Any ideas on what could be causing this?
This is what it looks like with no shadows on it.
This is what a shadow looks like from a distance.
This is the comparison up close.
I apologize for the low res images.....really!? 5.2 MB is a pretty low limit. This is a full shadow shot.
It's not as easy to see it in the pictures.....but it looks horrible. There are black areas and its almost as if all of the color has been taken out of it. I think the black areas are being caused by my normal, but I can't figure out why. I'm not a big fan of posting my materials, but here are the relevant parts.
Any help would be appreciated :)

A better image showing the issue would be great. However SSS will only work when the surface is directly lit because it's calculating how much light passes through when the light source is on the other side of the surface. If there is no light source visible then you won't see SSS. Light probes provide a generic, surrounding light environment so they can't be used in the calculation even if they are present.
