UE4 - Landscape Shadows

furys-death

Hey guys, just wondering if I could get a little help here. I've created a landscape via importing a height map. When I place the instanced material to the terrain the shadows look great, but then I build the lighting and they turn into hard edged shadows that look terrible.

I've tried increasing the light resolution all the way up to 8 with no better results. There is a screenshot below to better aid describing my problem.

Thanks in advanced
