No shadows on landscape

Hi,

I’ve been working on my first large outdoor scene and I’ve run into the issue of shadows not appearing on my landscape, as shown in the screenshots below. The shadows will not appear on the landscape for both my foliage (that I placed with the foliage tool) and static meshes I placed without the foliage tool, such as rocks. I was wondering if someone could help me fix this problem, as it’s crucial I get these shadows to work. :smiley:
