Hello, I have some bug in scene. I place my blueprint actor and make some work with it - add/remove trigger zone. When I delete it frome scene - nav mesh not rebuild. Reopen scene or editor, clear old floor and add new not help me.
Edit: When I wrote and posted this topic, my navmesh did rebuild by “magic”.
Try deleting the Nav Mesh Bounds Volume and placing a new Nav Mesh Bounds Volume if you haven’t already tried that.
Also, try clicking the Build button to Build Paths and see if that helps it regenerate.
Let me know if that helps.
Sorry for late answer. When I try to fix this issue it fix own through 5 minutes.
