Upcoming update, Directional shadows improvements are much much better in last version. No more cascade blending issues or noise. End of pseudo compatibility with older versions, new version requires at least Unity 5.6.0. Still working on VR update with ContactShadows but everything else still on target for this week submission. I've also separated Directional Shadows from Spot/Point shadows code (in case you want only to use NGSS Directional Shadows). You can now just install the package and just drop the Directional shadow replacement in your Graphics Menu. PS: Unity 2017 compatibility will probably won't make it to this week update (crossing fingers).
