I'm at the part of the tutorial where I've added a clipped sprite as a child to the Hole game object. As soon as I do I get the error message in the Inspector 'Sprite type incompatible with Render Mesh setting. Please use Default render Mesh.' I've tried removing and re-adding the Clipped Sprite only to get the same message. I find I can hit play in Unity and it'll run but at no time do I see the mole graphic in the scene or game views. Any ideas about this?
