I am working on a new 3D application and created a new SceneKit Scene.scn, it seemed off when I couldn’t see the grid that usually would be on the x and y axis in a 3D program, just grey. I added a node then set the location to 0,0,0. It moved out of the viewport that is visible. But now I cannot get the viewport to move to see the node. I must have pinched to zoom too many times because now when I add an object, the position is at wild values and the object is not even seen on my screen. Can an I set the view of the viewport back to default? Or Center and zoom to be centred on an object? I am lost and I cannot find my objects.
