{{Entity infobox

| what = A box that says where bots can walk, baked into a navigation mesh
| exported = yes
}}
A '''Nav Region''' is a box that tells the editor where to work out the ground bots can walk on. The editor '''bakes''' the floors inside the box into a navigation mesh: the walkable area, with walls, ledges and obstacles cut out, sized for a player. Without one, bots cannot find their way round the map.

How to set up a whole map for bots is on [[Level Editor/Workflows/Bots and navigation|Bots and navigation]].

== Placing and baking ==
# Choose '''Functional > Nav Region'''. Set its '''Name''' and '''Extents''' in Tool Properties first if you like.
# Click to place it. A translucent box shows its extents.
# Move it and resize its '''Extents''' so the box covers every floor bots should use.
# Select it and choose '''Functional > Bake Selected NavRegion'''. With no region selected, every region in the map is baked. The status line says ''Baked N NavRegion(s), M polys total''.

The baked mesh shows in the viewport. Several regions may overlap or touch: the game joins them into one network. '''View > Show Nav Region Volumes''' shows or hides the boxes.

The bake is sized for the game's player (its width, height, step height and the steepest slope it can walk), so you do not set any of that.

== Tool settings ==
{{Property table start}}
{{Property row|name=Name|type=Text|default=NavRegion|desc=The new region's name.}}
{{Property row|name=Extents (world AABB filter) X, Y, Z|type=Metres, 0.5 to 4096|default=40, 8, 40|desc=The new region's box size.}}
{{Property table end}}
''After placing, select the region and use Functional → Bake Selected NavRegion to bake. Region, edge and detail settings live on the region's inspector.''

== Inspector ==

{{Property row|name=Bake On Export|type=Check box|default=On|desc=Bake again from the current geometry whenever you export, so the navigation always matches the map. Off exports the last bake as it is; only turn it off for a reason, and bake first.}}

{{Property row|name=Edge Max Length|type=0 to 50|default=12|desc=''Edges & Polygon.'' The longest edge along the outline of the walkable area.}}
{{Property row|name=Edge Max Error|type=0.1 to 3|default=1.3|desc=''Edges & Polygon.'' How far the outline may stray from the true edge of the floor. Lower is more exact and heavier.}}
{{Property row|name=Verts Per Polygon|type=3 to 12|default=6|desc=''Edges & Polygon.'' The most corners one navigation polygon may have.}}
{{Property row|name=Filter Low Hanging Obstacles|type=Check box|default=Off|desc=''Filter.'' Treat low obstacles a player can step over as walkable.}}
{{Property row|name=Filter Ledge Spans|type=Check box|default=Off|desc=''Filter.'' Remove the edges of drops, so bots do not walk along the very rim.}}
{{Property row|name=Filter Walkable Low Height Spans|type=Check box|default=Off|desc=''Filter.'' Remove floor with too little headroom for a player.}}
{{Property row|name=Navigation Layers|type=Layers|default=1|desc=''Layers.'' Which navigation layers the region is on. Leave at 1.}}
{{Property table end}}

== Tips ==
* A Nav Region inside a [[Level Editor/Entities/Anchor Platform|moving platform]] rides with it.
* Doors and team gates are handled for you at export: their doorways become pieces of navigation the game opens and shuts. See [[Level Editor/Entities/Door#In the game|Door]].
* A [[Level Editor/Tools/Terrain|terrain]] with '''Generate Navmesh''' on is baked at export too.
