Landscape shadow artifacts

ivars

When I render the lighting for my landscape terrain I get these annoying black spots, which I guess i s shadows, but they look terrible.

Is there a way to fix this, or maybe to turn off self shadowing on the landscape mesh?

I'm using a dominant directional light.

This is what it looks like:

Too low shadowmap res?

I tried increasing it from 1 to 8 with the only result of considerably longer render times but the blobs remain

Hmm. So you're using only one dominant directional light and no other lights?

What happens if you turn on the cascaded shadow maps in the light's properties and go close to the blobs? Do they disappear (and are they replaced with proper dynamic shadows)?
