What is the current behavior? the ThreeJS version Image Tracking Example is not working, it always show loading icon. If the current behavior is a bug, please provide the steps to reproduce. I down load the package and upload to my own website, I open the link AR.js/three.js/examples/nft.html and the scene always on loading icon.

I have a similar problem, it works with the trex image in the example, but when I change this image to a custom one it doesn't work and the app gets stuck on the "loading, please wait" message and never moves from here. Any ideas how to fix it?

why is the camera_param.dat being loaded from AWS? I was able to get NFT tracking to be responsive by directly loading the local file. However, the ar content itself isn't loading. The GLTF loader is working fine, the web console tells me that the scene and camera are visible and that an image / nft is being tracked --- but no content appears

(three.js version, btw)

What are you seeing in the web console?
