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; } }
