func_nav_attribute_region is a brush entity available in Left 4 Dead series. It holds nav attributes to be applied on regions of overlapping nav areas when a navigation mesh has finished generating with nav_generate/nav_generate_incremental. Great for attributes necessitated by large regions of nav areas; e.g. TheFINALEattribute.

Tip:In

, Attributes are automatically applied after this entity spawns in, which is also every new round.

Note:Attributes set will persist when a round ends!

Keyvalues

Name (targetname) <string>[ Edit ]: The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).

Crouch (crouch) <choices> (only in )

Stairs (stairs) <choices> (only in )
