Ok so i have a problem with lumen foliage. And trust me, i have read every single thread and tried everything. Hardware raytracing is on, console commands tried, indirect lighting maxed (looks ugly + still some dark parts), lower hemisphere is not black and so on.

As you can see on the image, the undersides of the foliage are extremely dark compared to anything else in the scene. No matter what I change, they stay almost pitch black and nothing helps. I've tried both subsurface leaf materials as well as two sided foliage. No matter what i change in post processing helps. Changing distance field lighting on and off does nothing, as neither does nanite cards (i've tried both on and off).

The leaves are masked billboards if that helps, changing opacity just changes how bright they are.

Btw the tree in the middle of the road is a static mesh, not made with a foliage tool like anything else. The building is there just for a reference.

Unreal 5.6

Help would be much appreciated.

Just figuring out how to make the leaves to cast non-black shadows would be a huge start.
