Esm vs esp for exterior navmeshing

[UndeadMartyr]

I'd like to start navmeshing exterior cells in a new worldspace mod but am not entirely clear on whether I need to convert to an esp first.

If you're using the vanilla GECK then it needs to be converted to an ESP first because it can't edit masters, if you're using something like the GECK extender then you can go right ahead as that can edit masters, if you do use the vanilla GECK be sure to convert it back to a master afterwards or the navmesh won't work properly.

Navmeshing doesn't work with esps?

 

I'm using GECK extender.

They tend to be buggy, you only need to set the master flag on the esp, you don't need to change the extension, with that flag set the game will treat it as a master.

I personally have never had an issue with navmeshing in an esp, but I have seen a lot of other folks complain about it. I'd like to know what I am doing differently than everyone else.

I have no idea, I have to set that flag on every mod with a navmesh or I get classic broken navmesh behaviour from NPCs, erratic movement, no movement, sandboxing ones bunching up when entering a cell, that sort of thing. I would dismiss it as a bug in just my game if so many others hadn't reported the same thing and there are a lot of mods out there that have set the flag, I'm sure we're all familiar with this overly dramatic message...

I wonder if the author of this mod knows the answer? he seems to be knowledgeable. https://www.nexusmods.com/newvegas/mods/81003
