Subsurface without movable SkyLight?

Hello!

In UE 4.10 the movable SkyLight was ignored by using subsurface color.
Now in 4.12 it works also with movable SkyLight.
But is there a way to block the movable SkyLight again from subsurface like in UE 4.10?

Cause I use grass that looks great with a very bright subsurface color in the sun but now in UE4.12 with the movable SkyLight is much too bright in the shadows of other objects.

What can I do?
Thanks for helping me and sorry for my humble english. :wink:
