How to properly optimize large maps

Hey, I am currently working on recreating a part of the Valles Marineris in Unreal using a landscape.
The map is several kilometers large and I have some mountain assets to cover the map edges, but otherwise it’s mostly empty aside from some caves.

I understand that the map is quite large but the loading times have been pretty atrocious and I was curious if there are any good ways to properly optimize such large landscapes to make the project accessible to lower spec PCs? (I have a 9800X3D and an AMD rx 9070 xt as well as 64gb ram)

Use meshes. saves you all the problems you will get and around 40% performance.

Build the environment in a DCC like Houdini. it’s got everything you need to do it right. you just have to sort out how to part it up into slices for occlusion purposes - and how to generate good LODs.
