So I updated the actual Plaza model a bit. I removed the stupid web panel as lots of people have web disabled and were missing out. The video was embedded into the asset itself and the sound added to the scene.
The two advert screens on the side were replaced, removing the image panels and embedding images in the asset, the Cylinder door was also replaced with a embedded door in the asset. Lot's less to add in the scene now.
The Postbox was re-instated where it should be and the Amiibo box was added at the back.
As a bonus there is an Inkling Amiibo in it too!
