Landscape Not Receiving Light

Hi

I am making a forest scene with a road thru the trees.

I’m trying to now light the scene (direction + skyLight + Light Importance Volume around it) and expect some sort of dapply light effect onto the landscape from my trees. However what I am getting is purely shadowed landscape (even where there are no trees) and just dappled effect on the foliage.
Seems no light is direct light i ■■■■■■■■ the landscape…even when not populated with trees.

Have tried combinations of static, movable, etc but cant work it out?

Ideas?

could be due to a multitude of issues. Hard to answer without a fully in depth explanation.
