### Examples

```csharp
using UnityEngine;
using UnityEditor;
using System.Collections;

public class MyPlayer : MonoBehaviour
{
    public IEnumerator Start()
    {
        // This will load all objects in the fbx and return a single Mesh object.
        Mesh m = AssetDatabase.LoadAssetAtPath<Mesh>("Assets/test.fbx");

        AssetDatabase.TryGetGUIDAndLocalFileIdentifier(m, out string guid, out long localId);

        // At some point after the Mesh may or may not have unloaded we can reload just the mesh
        AssetDatabaseLoadOperation op = AssetDatabase.LoadObjectAsync("Assets/test.fbx", localId);

        // yield until the operation is completed
        while (!op.isDone)
            yield return null;

        Mesh reloadedMesh = (Mesh)op.LoadedObject;
    }
