How to correctly load new mesh?

MeshFilter meshfilt = Player.GetComponent();
meshfilt.mesh = Resources.Load(“Corner”) as Mesh;

I’m trying load new mesh to meshfilter but when I hit play button the mesh name has been changed to NONE

Mesh file is in Resources folder.

Don’t use Resources.Load for this.

Instead:

public Mesh replacementMesh;

private void Start()
{
  var meshFilter = Player.GetComponent<MeshFilter>();
  meshFilter.mesh = replacementMesh;
}

and then drag the mesh in question into the inspector.
