[RELEASED] for UE4: Complete Sky and Weather System

I am not able to get the cloud shadow to draw.
-UE4 is .1 and branch of .
-CloudShadow render target is applied to Cloud RT slot in the Sequence Actor in the scene
-I can change the cloud settings, play, and see the CloudShadow image changing as clouds move, but I don’t see it applying to the sun light and casting shadow on the terrain.
Any help or suggestion appreciated, thanks.
