more about the KSM :http://player.youku.com/player.php/sid/XNDE1NTE3NzY=/v.swf
Note:KSM do not use the depthbuffer method to make shadows which sucks the famous antialias problem no matter how large the SM resolutions are.
their is also some shaders like SSS/reliefmaping and the old VSM/PCF code avaiable.if someone are interest in these codes ,I will be happy to make it to a simple C# .cs node easy to put it into your projects.
