title: Importing .scn file to scene from URL with textures
body: <p>I am using ARKit for my application and I try to dynamically load .scn files from web-server</p>
  
  <p>Here is a part of my code</p>
  
  <pre><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")
      }
  </code></pre>
  
  <p>here <code>box.scn</code> contains textures. And I got an error</p>

  <p>Why Scenekit tries to load this textures from local file ? 
  How can I fix it?</p>
