    Shadowing on masked objects.

    Im working right now with a wheat field which looks fine except one thing, the shadowing is a bit off. I have a Dominant Directional Light in the scene with standard settings except lowered brightness and changed color.
    Results now:

    Front


    Back


    As you see the shadows don't really look nice or realistic, is there a way to soften up the shadows on the back side as a way to fake light going through?
    Thanks in advance!

    You can add slight emissive and decrease diffuse.

      you can use cascaded shadow maps for more realistic look.
      another way - don't use two sided material, create polygons for both sides with unique lightmap UVs.
      and the best way - your grass material can be unlit with emissive. it's very cheap but not so realistic.

        Tried using emissive, didnt look that well and if I use a light on it it doesnt look good at all so either cascaded shadow maps or more polys then, is there a good tutorial or guide on how to use cascaded shadow maps, I have no idea how to use them in UDK so :S

          Dominant Directional Light, and just enable the cascaded shadowmaps by increasing its radius and resolution.

              Ok Thanks alot for taking the time to answer
              I just got one more question :P
              Is there a difference in performance by doing it this way? Is this alot more costly?

                Dynamic shadows will always come with a greater cost. Baked in shadows have a much smaller impact on performance at the cost of Dynamic shadow interactions.

                  How about a transmission mask?
