URGENT: Static mesh keeps disappearing

Hello,

I’ve tried several meshes and even tried placing blueprints into the scene and the meshes keep appearing at a certain point when the camera gets close.

In the far distance, I need the mesh to stay visible the whole time. The strange thing is, this works perfectly in the viewport and MRQ but when I render I get these weird pop-ins.

Please help. Deadline looming.
