Navmesh for runtime loaded level instances?

Development World Creation

I have 4x4km map that uses world partition.
On some locations there are random “Points of interest”'s that gets loaded, as level instances, during runtime.
I am trying to figure out what is the best way to go about when it comes to the navmesh for this.

Ideally I would like to have a big prebuilt one that covers the entire landscape. Then when the “POIs” are loaded it would dirty those “tiles” and regenerate only there when those are loaded. And then do nothing else.

Or even better, if it is possible to pregenerate a smaller navmesh in the subleves/level instances and have those merge or sit on top of the bigger navmesh once they are loaded.

Any ideas how to do something like that?
Thanks in advance!

Its not that its never going to work, its that … well… its probably never going to work.

Try using Nav Invokers and the runtime generated stuff instead.

The static version of nav mesh is only occasionally useful - and i have bever experienced it working on anything bigger than 1km^2 personally.
