title: New to A-Frame and coding, trying to load a .gtlf model but not working
body: <p>New to A-frame and coding, trying to display a 3d scanned object on a marker. I upload a .gtlf to my asset folder and it's not loading when viewing the Hiro marker on my Galaxy s9+</p>
  
  <p>I've added (scale="0.2 0.2 0.2") but that doesn't work.</p>
  
  <p>Used <a href="http://github.khronos.org/glTF-Validator/" rel="nofollow noreferrer">http://github.khronos.org/glTF-Validator/</a> to make sure my .gtlf is valid and it is.</p>
  
  <p>Tried both .gtlf and .glb to see if that was the issue but both doesn't load.</p>

        You'll need to have &lt;a href="https://jeromeetienne.github.io/AR.js/data/images/HIRO.jpg"&gt;this image&lt;/a&gt; printed or just displaying on your phone!
