Hey there @walemmlis!Have you tried manually rebuilding the navigation using the command RebuildNavigation?If so, this might be that weirdness with multiplayer since I see your project up there. . i used Movedirectlytowards but Ai behavior tree just looping, there is no move.

But it seems as if the nav mesh doesn't show up in standalone mode. The agent radius on the navmesh is as low as I Hi, On my project we are having some issues with navigation meshes. It worked for me, on 5. 5 continues to improve the UE5 toolset. It returns navigation path reference that can be used to get an array of vectors. So when sub-level is streamed in/out tiles will be attached/detached to navmesh. Go to the Place Actors panel and under the In this guide we are showing you how to set up a NavMesh and basic AI Character in Unreal Engine 5. The initial state will have the NavMesh in this area start off disabled and then change to become active upon being triggered. Try looking into “Find Path to Location Synchronously”. It queries navmesh and returns a valid destination (this will eventually be more complex) then in my class blueprint I have a variable which is set to level blueprint. I created a level instance containing a landscape and a navmesh bound volume. So far, I have a simple sliding door that moves when any object In Unreal Engine 5 (UE5), the integration of Recast navmesh allows developers to create efficient navigation systems tailored to their specific AI needs.
