First you will need to bring up the page with the model.

If your model has Marmoset Viewer you'll see a little monkey head icon.

Press F12 and it will bring up Dev Tools. It should be blank here.

Now click on the Marmoset Viewer icon and youll start to see some stuff appear.

Find the file called .mview and double click it. It will then download to your downloads folder.

Once .mview is downloaded use Noesis to open it. You'll need the script below. Place script in Noesis/plugins/python folder.
