I am trying to have the meshing subsystem mesh toggle between being transparent and not transparent with the menu button . However I find that only _some_ of the mesh is getting changed. Most of the mesh remains in the original color/opacity. It's as if multiple instances of the Mesh Prefab are being created and used...? Any suggestions on how to change all of the mesh? Thank you.

Here's my code to toggle the mesh opacity:

```auto
    private void HandleOnMenu(InputAction.CallbackContext obj)
    {
        Renderer r = meshController.GetComponent<MeshingSubsystemComponent>().meshPrefab.GetComponent<Renderer>();
        if (r.material.color.a == 0.0f) {
            r.material.color = new Color(1,1,1, 2.0f/255.0f);
        } else {
            r.material.color = new Color(1,1,1, 0.0f);
        }
    }

```

Hi @paklnet  
you could try using

> r.sharedMaterial.color

instead if you want to effect all objects using that material
