Update: DynamicNavMesh allows to exclude specific navmesh source roots - Ghostships register to be excluded, since they have their own baked navmesh - [editor-only] Added logic to exclude all roots from the client scene This CL also has some temp ghostship debug code (offsets navmesh to validate it) Tests: in water world spawned a GhostShip and enabled AI - only backed navmesh popped into existence. AI didn't spawn - need to investigate next
