Syntax
FFilterNavDataDelegate ShouldUseGeometryDelegate
Remarks
Called to check if hosted geometry should be used for given FNavDataConfig. If not set then "true" is assumed. Might want to set bUseVirtualGeometryFilteringAndDirtying to true in the Navmesh class you are excluding geometry from. This will improve cpu performance by stopping the navmesh from dirtying tiles requested by actors being excluded by this delegate.
