NavMesh won't bake at all

Viewed 10271

I've attempted to bake a Navigation Mesh in Unity3D on a plane with no success. I haven't had this problem until recently, around the 2020.1 release date. I set the plane to navigation static, walkable, and baked the navigation mesh with the plane selected. A NavMesh object was created. The 'Source Bounds Extent' becomes very small after baking. The navigation mesh does not appear on the screen at all, when normally it should appear in blue. Wondering if anyone else had this problem recently or if there is something I can do to correct it.

This is a problem I've had very recently also but I have fixed it by turning on Gizmos. The Navmesh is actually there, but you just cannot see it. Turn on Gizmos (on the top of the scene window) to see the Navmesh fully baked! If the above suggestion does not work, try checking the Walkable layer is on the target object.

I fixed this problem by duplicating the gameobject I have my tilemaps in.

you need to disable all other objects in your scene. then bake your active static mesh.

I also, had the same problem, I put a group of pieces to static mesh, then baked, and it did nothing. So, I tried the save button, then when I tried another group and made it static mesh and hit the bake button it worked.

Try saving a scene before baking. It won't work if there is no scene present.
