Did a distance based tessellation to test the performance improvements (if any), but the landscape appears in chunks as I fly around. (It’s not a world composition).

Hey ,
It looks like you are experiencing a bounds issue. Try extending the Negative and Positive ZBounds for the landscape. The flickering and disappearing of meshes/components are sometimes the cause of World Position Offset pushing the object past its bounds. It looks like you are using WPO in your material. I would also be sure to set the Static Lighting LOD to the default, just for testing purposes.
Let me know if you are still experiencing the issue after trying the suggested changes.
Thanks,
