Import a .scn file into a scene from a texture URL

Question

I am using ARKit for my application and I am trying to dynamically download .scn files from a web server

Here is part of my code

    let url = URL(string: "http://192.168.0.31:1234/5a27e09cbad20a7a03ad5d80/box/box.scn")
    if let objectScene = try? SCNScene(url: url!, options: [.overrideAssetURLs: true]) {
        print("load success")
        let node = SCNNode()
        for childNode in objectScene.rootNode.childNodes {
            node.addChildNode(childNode)
        }

        sceneView.scene.rootNode.addChildNode(node)
    } else {
        print("error loading")
    }

box.scncontains textures here . And I got an error message

Failed to load: C3DImage 0x1c00f6f80 src: file: ///var/containers/Bundle/Application/110F7AB6-00F8-4E5B-B843-46551A23CB7F/ar.app/maps/CMU_Split_Face_Running_200x400_bump.jpg 0.00 [0000] 0.0000.00.000000 [0000] 000000]

Why is Scenekit trying to load these textures from a local file? How can i fix this?

, . , .scn , .

.scn :

do {
        let scene = try SCNScene(url: URL(fileURLWithPath: "YourDownloadedScnFilePath") , options: nil)

        // Set the scene to the view
        sceneView.scene = scene
    } catch {
        print("ERROR loading scene")
    }
