UE 5.1 procedural Foliage + Shadow Maps (CSM Shadows) bugged?

When using the procedural Foliage or Foliage Painter + setting the shadows to be “Shadow Maps” instead of the expansive “Virtual Shadow Maps” i get some strange results. The Shadows are disappearing when i rotate the camera to a specific angle (culling?).

When i place a static mesh of the tree i dont get the same problem.

Is this a bug in the new 5.1 Release or am i missing any new settings?

Thank You

It only happens when the sun is very close to the horizon (f.E. 07:00 am). I’m using standard settings for the CSM Shadows…

Did you find a solution for this problem in 5.1?
