Clear NavMeshSurface

How do you clear a NavMeshSurface?

I have tried

Code (CSharp):

1. NavMeshData.Destroy(CurrentFloorInstance.GetComponent<NavMeshSurface>().navMeshData);

and

Code (CSharp):

1. CurrentFloorInstance.GetComponent<NavMeshSurface>().navMeshData = new NavMeshData();

and

Code (CSharp):

1. CurrentFloorInstance.GetComponent<NavMeshSurface>().RemoveData();

I'm using GetComponent<NavMeshSurface>().BuildNavMesh() on load of a level to build it. But on each level load the nav mesh data from the previous level still seems to be there as well.

Additionaly I'm destroying the gameObject the navmesh component is on at the start of the level. But it seems when I instantiate it again, the old navmesh data is still hanging around.

Cheers

Did u ever solve this? I am having the same issue.

 

Code (CSharp):

1. NavMesh.RemoveAllNavMeshData();

or

Code (CSharp):

1. NavMesh.RemoveNavMeshData(YourNavMesh);

This works for me

 

I had the same problem, However I solved it with this idea: You can move the first scene so it does not overlapped with the new baked navmesh.
Note: Make sure to delete the old navmesh.asset

 

1. NavMesh.RemoveAllNavMeshData(); // its Work
