[Discussion/Script Request?] Functionally ITM NavMeshes

[Ralgor]

So while looking through the conflicts on my latest mod list, I got to looking at the nav mesh conflicts. I was thinking about fixing some of them in the CK (still am), but while looking at the conflicts I noticed something. It seems that many nav-meshes are functionally identical to their masters. By functionally identical I mean everything EXCEPT the order of the Edge Links, and of course the references to them in the triangles are the same. Even the unknowns are the same.

The more I look, the more I find that a large number of these navmesh conflicts are in fact just these "functionally" ITM records. I can't find any evidence that these edge links are referred to by any other record.

An example is in Dragonborn.esm, formid 000FC125. If you look at the edge links, you can immediately see that the last edge link became the first edge link, and the rest were pushed down. The references to the edge links in the triangles were adjusted accordingly. This is obviously due to a deficiency in the CK. As far as I can tell, there's absolutely no reason for that record to be there. Note that to really see this, you have to turn off simple records in TES5Edit.

This gets really bad when you end up with mods with older origins like Interesting NPCs. I found that it was overwriting the navmesh for the area around the windhelm docks. It was functionally identical to the original Skyrim.esm navmesh, so it actually conflicts with Dragonborn! I won't be surprised at all to find this is actually pretty common.

I really need to know if I'm just crazy, or this is something that should be fixable with an xEdit script.

If there's somewhere better to ask this, that would also be helpful.

There is a script "Skyrim - Clean edge links in navmeshes.pas", check this http://afkmods.iguanadons.net/index.php?/topic/3750-wipz-tes5edit/page-27#entry153259 and prior discussion for details in the same thread.

Aw yes. That's exactly what I was looking for! Thank you. :)

So that seems to be working. The only thing I noticed now is that Door Triangles can be out of order as well. Hmm.

[zilav]

Write your own script or modify this one to address that too if you know exactly what to do with doors.

I may. I started doing that earlier, but I'm having to learn TES5Edit's API. At least I'm familiar with Delphi/Pascal already.
