I've got a few questions about this topic.

1. What's the best way to navmesh a rather small world space, like an island?

2. Is it possible to autogenerate navmesh per cell basis? Let's say I have like a 4 cell playground, can I autogenerate only in those 4 cells?

i find manually navmeshing the easiest

im not sure about auto doing it tho

i second the manual navmeshing. i find the autogenerating feature to be really messy and you end up spending as much or more time cleaning it up than if you did it manually from scratch

Navmeshing a world space that has like 100 or so cells manually... That'll take ages.

so will cleaning it up after autogenerating. there is no quick "tighten up the grafx on level 3" button press for these kinds of things unfortunately

I haven't even figured out how to MAKE a viable worldspace, even using "use data" for Tamriel at a given location...if it's supposed to inherit the terrain info from the parent location, it does not do so when I try to do it...I don't suppose anyone can write a short tutorial on how to make a local worldspace so you can set up a quest in a "familiar" area without actually modifying the area by making a worldspace that loads the terrain info so you can make your local temporary changes, teleport the player in, play out a scene, then teleport the player out?

Does anyone know if it's possible to autogenerate navmesh per cell basis? Like if I only want it to be made in 3 cells.

I accidently did it once. So I know it's possible. But Maual Navmeshing is the way to go. I've found generation to be a straight PITA.

But do you know how you did it?
