title: Mapbox GL JS + Custom 3D Layer (three.js): flicker and disappears
body: <p>I'm trying to add multiple 3D models to a custom mapbox layer. I'm testing with a single 3d model first, similar to this example (<a href="https://docs.mapbox.com/mapbox-gl-js/example/add-3d-model/" rel="nofollow noreferrer">https://docs.mapbox.com/mapbox-gl-js/example/add-3d-model/</a>) but with a different gltf file.</p>
  <p>The problem is that the model flickers then disappears and i'm unsure how to begin to troubleshoot this. Perhaps, there needs to be customized settings for each model?</p>
