bUseExtraTopCellWhenMarkingAreas

Expand the top of the area nav modifier's bounds by one cell height when applying to the navmesh.

Windows

MacOS

Linux

Syntax

uint32 bUseExtraTopCellWhenMarkingAreas: 1

Remarks

Expand the top of the area nav modifier's bounds by one cell height when applying to the navmesh. If unset, navmesh on top of surfaces might not be marked by marking bounds flush with top surfaces (since navmesh is generated slightly above collision, depending on cell height).
