 `Mesh` holds a vertex buffer, an index buffer, and the number of indices in the mesh. We're using an `usize` for the material. This `usize` will be used to index the `materials` list when it comes time to draw.

 Before that though we need to actually load the model and save it to `State`. Put the following in `State::new()`.
 
 ```rust
-let (obj_model, cmds) = model::Model::load(&device, "code/beginner/tutorial9-models/src/res/cube.obj").unwrap();
+let (obj_model, cmds) = model::Model::load(
+    &device,

+).unwrap();
 ```
 
 The path to the obj will be different for you, so keep that in mind.
