Hi. Im currently programming an export function for my arkit app. The user should have the possibility to export the scene that he created. Unfortanatly always only one node gets exported. How can I export all nodes? let scene2 = SCNScene() let documentsPath = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first! let timeInterval = Date().timeIntervalSince1970 * 1000 let filename = String(format: "export_%d.dae", timeInterval) let exportUrl = documentsPath.appendingPathComponent(filename) scene2.write(to: exportUrl, options: nil, delegate: nil, progressHandler: nil);
