Lumen vs Path Tracing Culling

Hello,

I am working on a scene that has many speedtree assets.

There are two issues:

  1. When I foliage paint, there are sometimes random rotation on placement. I have disabled Random Yaw.

  2. Using Lumen and Pathtracing gives different culling behaviour, affecting the density of the trees.

Lumen:

Path Tracing:

I wish to have the correct density, which seems like the path traced one.

thank you
