Please help me with this glitch

I’m relatively new to unreal engine, and I’m designing a landscape for a game. It looks round and organic from up close, but when I back up it flattens, grows boxy, and the black grid lines appear. Help?

Sounds like LOD settings on your landscape terrain. Don’t know how/where the settings are for landscapes to change that, I know in the mesh editor it is in the details panel but I don’t know for landscape in particular. But I am pretty sure it is not a glitch but an actual setting to save performance.

Thank you!
