I have this code, and want to set the defaultCameraController.maximumVerticalAngle = 0.001 to disable up/down rotation of camera. How can this property be set in SwiftUI? import SwiftUI import SceneKit struct ContentView: View {     var scene = SCNScene(named: "LowPolyCopNew.usdz")     var body: some View {         VStack{             SceneView(scene: scene, options: [.allowsCameraControl, .autoenablesDefaultLighting])             .frame(width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height / 2)         Spacer(minLength: 0)         }     } }

How can you set the resolution in scenekit?I would like to render the scenekit view at half the resolution and then scale it up. (I'm hoping this will give a performance boost to my game at the cost of non retina graphics)

I need to run sceneView.projectPoint a couple of 100 times in a loop, it freezes my app regularly... not always. Sometimes it freezes for a second sometimes for 10 seconds.Any ideas?
