In Unreal 5.4.4, I followed this guide to build a static partitioned NavMesh.
When starting the game from the editor, it shows with “show navigation” and works perfectly. However, after packaging the game (either Debug and Development mode), it is missing and not working. NavDataChunks actors are correctly loaded with world partition, and RecastNavMesh is present also in packaged game.
Here are two screenshots from editor and built:
If I do the exactly same steps in another newly created map, or in a new project, it also works after build, but not in the main map of my game. Unfortunately, the map is very big and complex so it would be impossible to move everything to a new map.
Does anyone know wat could be causing this and how to try to solve?
