Here’s my new page about USD and glTF resources: https://www.realtimerendering.com/usd_gltf.html – if you see anything missing or wrong, let me know. I’m no expert, still learning. Which is in part why I put this page up, to get feedback.
This past year I made two minor contributions to the USD Working Group Assets repo. Being involved in the ASWF‘s activities and Slack channel has been a great help in learning about USD (and also a bit about glTF along the way). Fun thing: if you have an iPhone, click here – I like that Apple’s AR Quick Look is simply built in. Here’s one Minecrafty test model on my office floor.
