Adding custom prefab to helloar scene

Hi All,

I have a custom dae model that i want to use as the prefab on the HelloAR arcore example.

I have changed it in the example controller by dragging my model into the "Andy Plane Prefab" section, but when the app finds a plane and i click on the screen i no longer see through my camera.

The model appears, but the background is now the scene background as viewed in unity.

Id also like to make the plane detector disappear when the model is placed on a plane, but if i should put that in a new post thats fine.
