- Added flag in FNavigationRelevantData to indicates elements that want to skip dirty areas when added/removed from the NavigationOctree. - Method ShouldSkipDirtyAreaOnAddOrRemove has been added to INavRelevantInterface to control the flag. - UpdateNavOctreeElementBounds now takes a list of dirty areas instead of a single area to allow batched modifications. UInstancedStaticMeshComponent updates: - Added a cache for navigation bounds - Implements ShouldSkipDirtyAreaOnAddOrRemove so we don't dirty the whole area covered by the instances on registration but only a list of explicit areas using the instances. - Added PartialNavigationUpdates for batched modifications - Fixed partial update not sending the right area for the original position #rb aris.theophanidis #rb mikko.mononen #rb mieszko.zielinski #jira UE-195210#preflight 653bd451cc4d2d32203134e5 [CL 29185555 by yoan stamant in ue5-main branch]
