Resource:Navmeshing types and tips for Fallout 4

Navmeshing types and tips for Fallout 4 is a resource guide written by Glitchfinder and transcribed by Wanaming0.

Tips
A tip to follow those navmeshing tutorials: When navmeshing in the creation kit, make sure to start by right clicking the render window, selecting "Render Window Properties", and setting "Grids to load" to 1. The creation kit is very "helpful" about correcting navmeshes, and when working in certain areas of the commonwealth, even touching the navmesh of a cell can result in changes across a dozen other cells if they load in. (Never touch this setting for the game, though) The game engine has code that assumes a uGridsToLoad value of 5, so changing that setting for the game can have nasty side effects. Less so for the CK.

Red
Standard navmesh. NPCs can walk here.

Orange
Preferred pathing. Apply to selected triangles with P. NPCs find this "easier" to walk on.

Yellow
Float. Apply to selected triangles with ctrl+alt+F. NPCs don't like this one, but it gets used for pathfinding. Mostly found on places too steep to walk.

Pale/Grayish
No Large Creatures. Apply with ctrl+L. Large NPCs (as set with the "Use Large Actor Pathing" flag in the Race record) will not walk here. Check the museum of witchcraft (MuseumOfWitchcraft01) to see it in action.

Blue
Water. Apply with O. NPCs also don't like this one, but it will be used if they can swim.

Hot Pink
Precut. Applied by selecting an object and navmesh triangles, and then using the "Link Precuts for Selection" option in the Navmesh menu. This navmesh only exists if the linked objects do not. Do not use the "Precut All Scrappables" or "Create Precuts for Selection" options in the navmesh menu! All those options do is make a mess.
