=== Scrappable Objects === | |||
In Fallout 4, a new feature has been added to the navmesh; the ability to remove a placed object in-game, with the navmesh allowing actors to now navigate through the freed up space. This is done by associating specific triangles in the navmesh with specific, intersecting objects that have the necessary form list and object mod records that allows the player to scrap them in-game. | |||
To demonstrate this, the Commonwealth cell "FederalRationStockpileExt" will be used.[[File:Creation_Kit_-_Navmesh_-_Scrappable_Objects_001_-_Valid_Objects.png|thumb|alt=Screenshot of an object that qualifies for scrapping & in-game navmesh updating|The CarStationWagon06 object has all the necessary records (in a FormList used by a Constructible Object) to be scrapped in-game, which also qualifies it to affect the navmesh when scrapped.]] | |||
Select the object, and then press <code>Ctrl+E</code> to enable navmesh editing. At the top of the window, click <code>Navmesh</code>, then click <code>Link Precuts for Selection</code>. The navmesh will now have bright pink triangles; these are parts of the navmesh that are initially disabled, that the AI will navigate around. When the car object is scrapped, the triangles will then be enabled, allowing the AI to navigate through them. [[File:Creation_Kit_-_Navmesh_-_Scrappable_Objects_002_-_Linked_Precuts.png|thumb|alt=Screenshot of buggy navmesh editing; the selected car object should be visible, but isn't for some reason|The bright pink navmesh triangles are triangles that are initially disabled, and will be enabled once their linked object is scrapped.]] | |||
For some reason, this specific instance of the car object is not visible in navmesh editing mode, so it's hard to see why the car object takes up such a large area of the navmesh. The reason it does, is that it's bounding box intersects with those navmesh triangles, causing them to be linked to the object when we clicked <code>Link Precuts for Selection</code>. This can be resolved by essentially creating an empty space in the navmesh, around the object's bounding box, and then creating new navmesh triangles that better fit the car object. | |||
