LOD usage not uniform for Camera Zooming

Hi,

so the issue I’m currently facing is that if I zoom-in via the cinematic camera the LODs are not activated correctly. I have for example sometimes issues to properly show grass patches, while other foliage is correctly displayed.

I enabled the option “Use Field Of View for LOD” but still there are some issues…

Is there a special option on the materials? I would be really greatful for any lead!
