Hello people, how are you?

I was out from Skyrim modding for several months.

I've some question about navmesh and border region.

1. It's safe to add more navmesh in vanilla worldspace? None of the vanilla navmesh will be touched except for connecting them to the new navmesh triangles.

2. As you know, you cannot pass border region ingame, however the NPCs can go outside the border region?

Thank you very much

1. It is safe to extend vanilla navmesh using new navmesh. However you cannot safely connect two existing navmeshes as it counts as a deletion.

2. I can't answer that one I'm afraid
