I’m working on a UE 4.27 project where I need a static nav mesh for a large map build with world composition. I need the nav mesh to be static because I have AI roaming that I want to continue roaming even when sub levels are not loaded. In the editor this works well with a static nav mesh thats generated with all the sub levels loaded. I can see the nav mesh stays static even when the levels load and unload and my AI continue to navigate correctly. But for some reason when I try to launch the level my nav mesh disappears. There seems to still exist a RecastNavMesh-Default object which I believe holds the actual nav data, but when I try to show the nav mesh nothing is there, and my AI fail to find a navigable point on the nav mesh. What am I missing? Why doesnt the static nav mesh show up in the build?
