title: Have SCNCamera follow a node at a fixed distance?
body: <p>I have a SCNNode, and an SCNCamera. The camera is located up and in front of the node, and looks down on the node via an SCNLookAtConstraint that I have setup. However when the node moves laterally, the camera only rotates, instead of moving with the it. Is there any way to get the camera to move with the node?</p>
