title: "dae" 3D model side become transparent in iOS app
body: <p>I'm new to 3D models and try to make my test game in <a href="https://developer.apple.com/documentation/scenekit/" rel="nofollow noreferrer">SceneKit</a></p>
  <p>I use <a href="https://ru.wikipedia.org/wiki/Cinema_4D" rel="nofollow noreferrer">Cinema 4D</a> on Windows PC for creating 3D models.</p>
  <p>I want to add my texture with a transparent background on a side of a 3D object.</p>
  <p>But my texture makes the cube's side transparent instead of keep as it was.</p>
  <p>In Cinema 4D it displays as intended.
