The scope of your project seems to be way above what the traditional tools of Unreal Engine can offer. I suggest you find or create your own tools that doesn’t use nav meshes.

> million kilometers on different islands.

The further you stray from the origin of your level, the more inaccurate calculations will become.

Here is some further clarification regarding the terrain sizes: [UE5 - World Partition - Massive Map Sizes? - #6 by noone](https://forums.unrealengine.com/t/ue5-world-partition-massive-map-sizes/510107/6)

> The basic rule of what you will require for a computer for main memory and video memory for importing and loading all cells for various world sizes is:  
> 8km x 8km = 32GB memory and RTX-3050 8GB  
> 16km x 16km = 64GB memory and RTX-3080 10GB  
> 32km x 32km = 128GB memory and RTX-3090 24GB  
> 64km x 64km = 512GB memory and RTX-8000 48GB

According to the calculation, assuming everything scales linearly, you would need a PC with 16 Petabytes of RAM for about 1 million KM in size. This also assumes you will end up using the partition system.

Could you clarify why you would want to do what you are trying to do?
