Foliage randomly disappearing

I have a rather large level with foliage. While I’m somewhat near the center of the level, I have all foliage visible:

If I move outwards for a bit however, some of the foliage disappears:

Further still, all of it is gone:

Why might that be?

The foliage is in the persistent level. In the given example I move towards at least some of the foliage so it shouldn’t be distance culling either.

When i disable foliage culling ( foliage.DisableCull 1 ), the foliage still disappears.

same problem with foliage.Freeze

It may have to do with your graphic settings or your pc rig. Sometimes smaller things like foilage despawn or “disappear” when you have low graphical settings or render distance.

Thanks for the suggestion, but that would only explain distance culling. I can move further to a tree though, and it still disappears, if I move away too far from some certain point in the level (I believe it is the middle of the level, but I don’t know how to verify that).

Also, as far as I can tell it only happens in this particular level. Although it is by far the largest I’m working with, so that, too, is hard to verify.

FreezeRendering however does keep the Trees visible.
